| 1 | High-performance modified uni-traveling carrier photodiode integrated on a thin-film lithium niobate platform显示文摘Lithium niobate on insulator(LNOI)has become an intriguing platform for integrated photonics for applications in communications,microwave photonics,and computing.Whereas,integrated devices including modulators,resonators,and lasers with high performance have been recently realized on the LNOI platform,high-speed photodetectors,an essential building block in photonic integrated circuits,have not been demonstrated on LNOI yet.Here,we demonstrate for the first time,heterogeneously integrated modified uni-traveling carrier photodiodes on LNOI with a record-high bandwidth of 80 GHz and a responsivity of 0.6 A/W at a 1550-nm wavelength.The photodiodes are based on an n-down In GaAs/InP epitaxial layer structure that was optimized for high carrier transit time-limited bandwidth.Photodiode integration was achieved using a scalable wafer die bonding approach that is fully compatible with the LNOI platform. | XIANGWEN GUO LINBO SHAO LINGYAN HE KEVIN LUKE JESSE MORGAN KEYE SUN JUNYI GAO TA-CHING TZU YANG SHEN DEKANG CHEN BINGTIAN GUO FENGXIN YU QIANHUAN YU MASOUD JAFARI MARKO LONčAR MIAN ZHANG ANDREAS BELING | 2022 | Photonics Research2022，10，6： | 2 |
| 2 | Magnetic Properties of lT-TaS_(2)显示文摘The magnetic properties of 1T-TaS_(2) and 1T-Fe_(0.07)Ta_(0.93)S_(2) have been studied.Experimental results show that the phase transition temperature of IT-TaS_(2) is a function of the magnetic field.At low temperatures,both compounds are in a mixed state of charge density wave-spin density wave due to the coherent superposition of antifer-romagnetic coupling. | DAI Shouyu YU Chengtao LI Donghong FAN Shiyong JIN Jiucheng CAI Fengxin | 1995 | Chinese Physics Letters1995，12，10： | 0 |
