Formulas of the transfer functions are presented for a series-coupled microring resonant filter and the filtering characteristics of this device are investigated around the central wavelength of 1.55 μm.The simulation results show that when the number of the microring is 4,the amplitude coupling ratio between the channel and the microring is 0.25,that between two microrings is 0.022,and the flat box-like spectral response can be formed.The 3-dB bandwidth is about 0.2 nm,the insertion loss is about 1.5 dB,and the minimum of non-resonant light is close to -150 dB. 展开更多

A scheme of WDM+ OCDMA system employing optical hard-limiter(OHL) is proposed, and its performance of normalized throughput is analyzed. The upper bound of the normalized throughput is obtained when all the simultaneous users are equally allocated to different wavelength channels. The lower bound of the normalized throughput is obtained when all the simultaneous users are firstly allocated to the same wavelength channels. Compared with the performance of VVDM+ OCDMA system without OHL, both the upper bound and lower bound of the normalized throughput in WDM + OCDMA system with OHL can be improved. 展开更多

The quantum key distribution(QKD) has been entering the practical application era. Subsequently, hybrid quantum private communication with discrete-variable signals, continuous-variable signals, and classic optical signals becomes inevitable in the practical scenario. In this paper, we experimentally investigated the mutual effects between the discrete-variable QKD(DVQKD) and the continuous-variable QKD(CVQKD) via a fiber channel. The experimental results show that the DVQKD will be influenced by the continuous-variable quantum signals and classic optical signals, while the CVQKD is not sensitive to the discrete-variable quantum signals. 展开更多
