| 3 | Directional terahertz holography with thermally active Janus metasurface显示文摘Dynamic manipulation of electromagnetic(EM)waves with multiple degrees of freedom plays an essential role in enhancing information processing.Currently,an enormous challenge is to realize directional terahertz(THz)holography.Recently,it was demonstrated that Janus metasurfaces could produce distinct responses to EM waves from two opposite incident directions,making multiplexed dynamic manipulation of THz waves possible.Herein,we show that thermally activated THz Janus metasurfaces integrating with phase change materials on the meta-atoms can produce asymmetric transmission with the designed phase delays.Such reconfigurable Janus metasurfaces can achieve asymmetric focusing of THz wave and directional THz holography with free-space image projections,and particularly the information can be manipulated via temperature and incident THz wave direction.This work not only offers a common strategy for realizing the reconfigurability of Janus metasurfaces,but also shows possible applications in THz optical information encryption,data storage,and smart windows. | Benwen Chen Shengxin Yang Jian Chen Jingbo Wu Ke Chen Weili Li Yihui Tan Zhaosong Wang Hongsong Qiu Kebin Fan Caihong Zhang Huabing Wang Yijun Feng Yunbin He Biaobing Jin Xinglong Wu Jian Chen Peiheng Wu | 2023 | Light(Science & Applications)2023，12，6： | 1 |
| 4 | InP-based directly modulated monolithic integrated few-mode transmitter显示文摘A monolithic integrated few-mode transmitter comprising of two directly modulated distributed feedback lasers and a multimode-interference-coupler-based mode converter-multiplexer with 66% mode conversion efficiency was designed and demonstrated. A fundamental TE0 mode and a first-order TE1 mode were successfully generated from the transmitter, with the output power of 4 and 5.5 mW at a pump current of around 150 mA, respectively,at the common output port. The small signal modulation bandwidth of the TE0 and TE1 channels reached 17.4 and 14.7 GHz, respectively. Error-free 2 × 10-Gbit∕s direct modulation of the two-mode transmitter was demonstrated, with a power penalty of 4.3 dB between the TE0 mode and the TE1 mode at the bit error rate of 1 × 10^(-9). | ZHAOSONG LI DAN Lu YIMING HE FANGYUAN MENG XULIANG ZHOU JIAOQING PAN | 2018 | Photonics Research2018，6，5： | 1 |

| 7 | Asymmetric quantum well broadband thyristor laser显示文摘A broadband thyristor laser based on InGaAs/GaAs asymmetric quantum well(AQW) is fabricated by metal organic chemical vapor deposition(MOCVD). The 3-μm-wide Fabry–Perot(FP) ridge-waveguide laser shows an S-shape I-V characteristic and exhibits a flat-topped broadband optical spectrum coverage of ~27 nm(Δ_(-10) dB) at a center wavelength of ~1090 nm with a total output power of 137 mW under pulsed operation. The AQW structure was carefully designed to establish multiple energy states within, in order to broaden the gain spectrum. An obvious blue shift emission, which is not generally acquired in QW laser diodes, is observed in the broadening process of the optical spectrum as the injection current increases. This blue shift spectrum broadening is considered to result from the prominent band-filling effect enhanced by the multiple energy states of the AQW structure, as well as the optical feedback effect contributed by the thyristor laser structure. | Zhen Liu Jiaqi Wang Hongyan Yu Xuliang Zhou Weixi Chen Zhaosong Li Wei Wang Ying Ding Jiaoqing Pan | 2017 | Journal of Semiconductors2017，38，11： | 0 |
| 8 | InP-based monolithically integrated few-mode devices显示文摘Mode-division multiplexing(MDM) has become an increasingly important technology to further increase the transmission capacity of both optical-fiber-based communication networks, data centers and waveguidebased on-chip optical interconnects. Mode manipulation devices are indispensable in MDM system and have been widely studied in fiber, planar lightwave circuits, and silicon and InP based platforms. InP-based integration technology provides the easiest accessibility to bring together the functions of laser sources, modulators, and mode manipulation devices into a single chip, making it a promising solution for fully integrated few-mode transmitters in the MDM system. This paper reviews the recent progress in InP-based mode manipulation devices, including the few-mode converters, multiplexers, demultiplexers, and transmitters. The working principle, structures, and performance of InP-based few-mode devices are discussed. | Dan Lu Yiming He Zhaosong Li Lingjuan Zhao Wei Wang | 2018 | Journal of Semiconductors2018，39，10： | 0 |
