| 2 | Ablation and radar-wave transmission performances of the nitride ceramic matrix composites显示文摘The 2.5 dimensional silica fiber reinforced nitride matrix composites (2.5D SiO2f/Si3N4-BN) were prepared through the preceramic polymer impregnation pyro- lysis (PIP) method. The ablation and radar-wave transparent performances of the composite at high temperature were evaluated under arc jet. The composition and ablation surface microstructures were studied by X-ray diffraction (XRD) and scanning electron microscope (SEM). The results show that the 2.5D SiO2f/Si3N4-BN composites have a linear ablation rate of 0.33 mm/s and high radar-wave trans- parent ratio of 98.6%. The fused layer and the matrix are protected by each other, and no fused layer accumulates on the ablation surface. The nitride composite is a high-temperature ablation resistivity and microwave transparent material. | JIANG YongGang ZHANG ChangRui CAO Feng WANG SiQing HU HaiFeng QI GongJin | 2008 | Science China(Technological Sciences)2008，51，1： | 14 |
| 3 | Ultrasensitive magnetic field sensor based on an in-fiber Mach–Zehnder interferometer with a magnetic fluid component显示文摘An ultrasensitive magnetic field sensor based on a compact in-fiber Mach–Zehnder interferometer(MZI) created in twin-core fiber(TCF) is proposed, and its performance is experimentally demonstrated. A section of TCF was spliced between two sections of standard single-mode fibers, and then a microchannel was drilled through one core of the TCF by means of femtosecond laser micromachining. The TCF with one microchannel was then immersed in a water-based Fe_3O_4 magnetic fluid(MF), forming a direct component of the light propagation path,and then sealed in a capillary tube, achieving a magnetic sensing element, which merges the advantages of an MZI with an MF. Experiments were conducted to investigate the magnetic response of the proposed sensor. The developed magnetic field sensor exhibits a linear response within a measurement range from 5 to 9.5 m T and an ultrahigh sensitivity of 20.8 nm/m T, which, to our best knowledge, is 2 orders of magnitude greater than other previously reported magnetic sensors. The proposed sensor is expected to offer significant potential for detecting weak magnetic fields. | Zhengyong Li Changrui Liao Jun Song Ying Wang Feng Zhu Yiping Wang Xiaopeng Dong | 2016 | Photonics Research2016，4，5： | 6 |
| 4 | Review of Femtosecond-Laser-Inscribed Fiber Bragg Gratings:Fabrication Technologies and Sensing Applications显示文摘Fiber Bragg grating(FBG)is the most widely used optical fiber sensor due to its compact size,high sensitivity,and easiness for multiplexing.Conventional FBGs fabricated by using an ultraviolet(UV)laser phase-mask method require the sensitization of the optical fiber and could not be used at high temperatures.Recently,the fabrication of FBGs by using a femtosecond laser has attracted extensive interests due to its excellent flexibility in creating FBGs array or special FBGs with complex spectra.The femtosecond laser could also be used for inscribing various FBGs on almost all fiber types,even fibers without any photosensitivity.Such femtosecond-laser-induced FBGs exhibit excellent thermal stability,which is suitable for sensing in harsh environment.In this review,we present the historical developments and recent advances in the fabrication technologies and sensing applications of femtosecond-laser-inscribed FBGs.Firstly,the mechanism of femtosecond-laser-induced material modification is introduced.And then,three different fabrication tech no logies,i.e.,femtosecond laser phase mask technology,femtosecond laser holographic interferometry,and femtosecond laser direct writing technology,are discussed.Finally,the advances in high-temperature sensing applications and vector bending sensing applications of various femtosecond-laser-inscribed FBGs are summarized.Such femtosecond-laser-inscribed FBGs are promising in many industrial areas,such as aerospace vehicles,nuclear plants,oil and gas explorations,and advanced robotics in harsh environments. | Jun HE Baijie XU Xizhen XU Changrui LIAO Yiping WANG | 2021 | Photonic Sensors2021，11，2： | 6 |
| 5 | Single-mode helical Bragg grating waveguide created in a multimode coreless fiber by femtosecond laser direct writing显示文摘We demonstrate the fabrication of single-mode helical Bragg grating waveguides(HBGWs)in a multimode core-less fiber by using a femtosecond laser direct writing technique.This approach provides a single-step method for creating Bragg grating waveguides.Specifically,the unique helical structure in such an HBGW serves as a depressed cladding waveguide and also generates strong Bragg resonance due to its periodicity.Effects of pulse energy,helical diameter,and helical pitch used for fabricating HBGWs were studied,and a single-mode HBGW with a narrow bandwidth of 0.43 nm and a Bragg wavelength of 1546.50 nm was achieved by using appropriate parameters,including a diameter of 10μm and a helical pitch of 1.07μm.The measured cross-sectional refractive index profile indicates that a depressed cladding waveguide has been created in this single-mode HBGW.Moreover,five single-mode HBGWs with various Bragg wavelengths were successfully fabricated by controlling the helical pitch,and this technique could be used for achieving a wavelength-division-multiplexed HBGW array.Then,the temperature and strain responses of the fabricated single-mode HBGW were tested,exhibiting a temperature sensitivity of 11.65 pm/℃ and a strain sensitivity of 1.29 pm/με,respectively.In addition,the thermal stability of the single-mode HBGW was also studied by annealing at a high temperature of 700℃ for 15 h.The degeneration of the single-mode waveguide into a multimode waveguide was observed during the isothermal annealing process,and the peak reflection and the Bragg wavelength of the fundamental mode exhibited a decrease of∼7 dB and a“blue”shift of 0.36 nm.Hence,such a femtosecond laser directly written single-mode HBGW could be used in many applications,such as sapphire fiber sensors,photonic integrated circuits,and monolithic waveguide lasers. | JUN HE JIA HE XIZHEN XU BIN DU BAIJIE XU CHANGRUI LIAO ZHIYONG BAI YIPING WANG | 2021 | Photonics Research2021，9，10： | 4 |
| 6 | Fabrication and oxidation resistance of silicon nitride fiber reinforced silica matrix wave-transparent composites显示文摘Wave-transparent ceramic matrix composites for the high temperature use should possess excellent oxidation resistance. In this work, Si3N4f/SiO2 composites with different fiber content were fabricated by filament winding and sol gel method. The oxidation resistance was investigated by tracking the response of flexural strength to the testing temperature. The results show that the flexural strength and toughness of the composites with fiber content of over 37% can reach high levels at around 175.0 MPa and 6.2 MPa m^1/2, respectively. After 1 h oxidation at 1100℃, the flexural strength drops a lot but can still reach 114.4 MPa, which is high enough to ensure the safety of structures. However, when the oxidation temperature rises to 1200–1400℃, the flexural strengths continue to fall to a relatively low level at 50.0–66.4 MPa. The degradation at high temperatures is caused by the combination of over strong interfacial bonding, the damage of fiber and the crystallization of silica matrix. | Xuejin Yang Bin Li Duan Li Changwei Shao Changrui Zhang Chunrong Zou Kun Liu | 2019 | Journal of Materials Science & Technology2019，35，12： | 4 |
| 7 | Effects of heat treatment on properties of boron nitride fiber显示文摘The boron nitride fibers were heated at the range of 600-1400oC in flowing nitrogen and air, respectively, and the effects of heat treatment on the structure, composition and morphology of BN fibers were studied. The results showed that BN fibers exhibited smooth surfaces, and that t-BN was the main phase with a little B2O3 included. After heat treatment at 1400oC in nitrogen atmosphere, the fibers displayed rough surfaces with little change in mass. Better crystallinity was obtained with the increasing temperature. During heat treatment in air, the fibers were oxidized severely as the temperature went up, especially at 1400oC. The volatilization of B2O3, HBO2 and H3BO3 led to the pores on the surfaces of the fibers, while the boron oxide glaze and nitrogen gas produced during the oxidation process protected the fibers from further oxidation. | LI Duan ZHANG ChangRui LI Bin CAO Feng WANG SiQing | 2012 | Science China(Technological Sciences)2012，55，5： | 4 |
| 8 | Liquid modified photonic crystal fiber for simultaneous temperature and strain measurement显示文摘A liquid modified photonic crystal fiber(PCF)integrated with an embedded directional coupler and multi-mode interferometer is fabricated by infiltrating three adjacent air holes of the innermost layer with standard 1.48 refractive index liquids.The refractive index of the filled liquid is higher than that of background silica,which can not only support the transmitting rod modes but also the'liquid modified core'modes propagating between the PCF core and the liquid rods.Hence,the light propagating in the liquid modified core can be efficiently coupled into the satellite waveguides under the phase-matching conditions,resulting in a dramatic decrease of the resonant wavelength intensity.Furthermore,there is a multi-mode interference produced by modified core modes and rod modes.Such a compact(~0.91 cm)device integrated with an embedded coupler and interferometer is demonstrated for high-sensitivity simultaneous temperature(~14.72 nm∕℃)and strain(~13.01 pm∕με)measurement. | CHUPAO LIN YING WANG YIJIAN HUANG CHANGRUI LIAO ZHIYONG BAI MAOXIANG HOU ZHENGYONG LI YIPING WANG | 2017 | Photonics Research2017，5，2： | 3 |
| 9 | Fabrication of high performance 3D SiO_2/Si_3N_4 composite via perhydropolysilazane infiltration and pyrolysis显示文摘Perhydropolysilazane, a low viscosity preceramic polymer with good wettability and high char yield, was used to fabricate three-dimensional silica fiber reinforced silicon nitride matrix composites through the repeated infiltration-curing- pyrolysis cycles. With the increase of the pyrolysis temperature from T1, T2 to T3, the density of the composites increased all through, but the flexural strength showed a maximum value at T2 followed by a sharp decrease. The composite prepared at T2 exhibited a good ceramization of the preceramic polymer, a high flexural strength of 144.9 MPa and excellent dielectric property. The high performance of the composite resulted from the good state of the silica fibers, controlled fiber/matrix interfacial microstructures and high-purity dense silicon nitride matrix. | QI Gongjin ZHANG Changrui HU Haifeng CAO Feng WANG Siqing JIANG Yonggang | 2005 | Science China(Technological Sciences)2005，48，6： | 3 |
| 10 | Fiber-tip polymer clamped-beam probe for high-sensitivity nanoforce measurements显示文摘Micromanipulation and biological,material science,and medical applications often require to control or measure the forces asserted on small objects.Here,we demonstrate for the first time the microprinting of a novel fiber-tip-polymer clamped-beam probe micro-force sensor for the examination of biological samples.The proposed sensor consists of two bases,a clamped beam,and a force-sensing probe,which were developed using a femtosecond-laser-induced two-photon polymerization(TPP)technique.Based on the finite element method(FEM),the static performance of the structure was simulated to provide the basis for the structural design.A miniature all-fiber micro-force sensor of this type exhibited an ultrahigh force sensitivity of 1.51 nmμN−1,a detection limit of 54.9 nN,and an unambiguous sensor measurement range of~2.9 mN.The Young’s modulus of polydimethylsiloxane,a butterfly feeler,and human hair were successfully measured with the proposed sensor.To the best of our knowledge,this fiber sensor has the smallest force-detection limit in direct contact mode reported to date,comparable to that of an atomic force microscope(AFM).This approach opens new avenues towards the realization of small-footprint AFMs that could be easily adapted for use in outside specialized laboratories.As such,we believe that this device will be beneficial for high-precision biomedical and material science examination,and the proposed fabrication method provides a new route for the next generation of research on complex fiber-integrated polymer devices. | Mengqiang Zou Changrui Liao Shen Liu Cong Xiong Cong Zhao Jinlai Zhao Zongsong Gan Yanping Chen Kaiming Yang Dan Liu Ying Wang Yiping Wang | 2021 | Light(Science & Applications)2021，10，9： | 3 |

| 12 | Design and realization of 3D printed fiber-tip microcantilever probes applied to hydrogen sensing显示文摘Cantilevers in microelectromechanical systems have the advantages of non-labeling,real-time detection,positioning,and specificity.Rectangular solid,rectangular hollow,and triangular microcantilevers were fabricated on an optical fiber tip via two-photon polymerization.The mechanical properties were characterized using finite element simulations.Coating the microcantilever with a palladium film enabled high sensitivity and rapid hydrogen detection.The shape of the cantilever determines the sensitivity,whereas the thickness of the palladium film determines the response time.Additional microelectromechanical systems can be realized via polymerization combined with optical fibers. | Changrui Liao Cong Xiong Jinlai Zhao Mengqiang Zou Yuanyuan Zhao Bozhe Li Peng Ji Zhihao Cai Zongsong Gan Ying Wang Yiping Wang | 2022 | Light(Advanced Manufacturing)2022，3，1： | 2 |

| 14 | 3D printed fiber-optic nanomechanical bioprobe显示文摘Ultrasensitive nanomechanical instruments,e.g.atomic force microscopy(AFM),can be used to perform delicate biomechanical measurements and reveal the complex mechanical environment of biological processes.However,these instruments are limited because of their size and complex feedback system.In this study,we demonstrate a miniature fiber optical nanomechanical probe(FONP)that can be used to detect the mechanical properties of single cells and in vivo tissue measurements.A FONP that can operate in air and in liquids was developed by programming a microcantilever probe on the end face of a single-mode fiber using femtosecond laser two-photon polymerization nanolithography.To realize stiffness matching of the FONP and sample,a strategy of customizing the microcantilever’s spring constant according to the sample was proposed based on structure-correlated mechanics.As a proof-of concept,three FONPs with spring constants varying from 0.421 N m^(−1)to 52.6 N m^(−1)by more than two orders of magnitude were prepared.The highest microforce sensitivity was 54.5 nmμN^(−1)and the detection limit was 2.1 nN.The Young’s modulus of heterogeneous soft materials,such as polydimethylsiloxane,muscle tissue of living mice,onion cells,and MCF-7 cells,were successfully measured,which validating the broad applicability of this method.Our strategy provides a universal protocol for directly programming fiber-optic AFMs.Moreover,this method has no special requirements for the size and shape of living biological samples,which is infeasible when using commercial AFMs.FONP has made substantial progress in realizing basic biological discoveries,which may create new biomedical applications that cannot be realized by current AFMs. | Mengqiang Zou Changrui Liao Yanping Chen Lei Xu Shuo Tang Gaixia Xu Ke Ma Jiangtao Zhou Zhihao Cai Bozhe Li Cong Zhao Zhourui Xu Yuanyuan Shen Shen Liu Ying Wang Zongsong Gan Hao Wang Xuming Zhang Sandor Kasas Yiping Wang | 2023 | International Journal of Extreme Manufacturing2023，5，1： | 1 |

| 19 | Defend Against Adversarial Samples by Using Perceptual Hash显示文摘Image classifiers that based on Deep Neural Networks(DNNs)have been proved to be easily fooled by well-designed perturbations.Previous defense methods have the limitations of requiring expensive computation or reducing the accuracy of the image classifiers.In this paper,we propose a novel defense method which based on perceptual hash.Our main goal is to destroy the process of perturbations generation by comparing the similarities of images thus achieve the purpose of defense.To verify our idea,we defended against two main attack methods(a white-box attack and a black-box attack)in different DNN-based image classifiers and show that,after using our defense method,the attack-success-rate for all DNN-based image classifiers decreases significantly.More specifically,for the white-box attack,the attack-success-rate is reduced by an average of 36.3%.For the black-box attack,the average attack-success-rate of targeted attack and non-targeted attack has been reduced by 72.8%and 76.7%respectively.The proposed method is a simple and effective defense method and provides a new way to defend against adversarial samples. | Changrui Liu Dengpan Ye Yueyun Shang Shunzhi Jiang Shiyu Li Yuan Mei Liqiang Wang | 2020 | Computers, Materials & Continua2020，，3： | 1 |
