    A SPAD-Based Configurable Photon Counting System

    A SPAD-Based Configurable Photon Counting System by Shijie Deng, Alan P. Morrison, Chuanxin Teng, Houquan Liu, Ming Chen, Hongyan Yang, Ronghui Xu, Libo Yuan, Hongchang Deng

    Published 2019-01-01

    In this work, a single photon avalanche diode (SPAD) based configurable photon counting system is developed. The photon counting system is able to operate in three working modes to enhance the system's different performance characteristics for various use cases (e.g., strong/we...

    Coherent Perfect Absorber Based on Antisymmetric Metasurface With Gain Material

    Coherent Perfect Absorber Based on Antisymmetric Metasurface With Gain Material by Ming Chen, Chen Chen, Shijie Deng, Chongyun Wang, Houquan Liu, Chuanxin Teng, Yu Cheng, Hongyan Yang, Ronghui Xu, Hongchang Deng, Libo Yuan

    Published 2020-01-01

    In this paper, we proposed a two ports coherent perfect absorber based on antisymmetric metasurface with gain material which is able to effectively regulate the absorption of the coherent incident wave under the condition of unequal incident intensities. This design overcomes the limitation that exi...
