摘要
采用光子灯笼作为模式复用/解复用器,搭建了6×6的模分复用通信实验系统,利用6个模式作为独立传输信道,采用相位调制-相干检测的方式,通过离线信号处理,在10 km少模光纤的传输条件下实现了6×8.5 Gbit/s信号的良好传输。实验结果表明:当LP01、LP11a、LP11b、LP21a、LP21b、LP02模式的接收功率分别为-37.84 dBm、-36.47 dBm、-36.20 dBm、-35.27 dBm、-35.37 dBm、-35.79 dBm时,各路信号的误码率均可达到10 -3以下。
Abstract
In this study, we have developed a 6×6 mode-division-multiplexing communication experimental system using a photon lantern as the mode multiplexer/demultiplexer. Further, we can achieve a signal transmission rate of 6×8.5 Gbit/s in a 10-km few-mode fiber using a phase modulation and coherent detection system via offline digital signal processing. The results denote that the bit error rate of each signal can be less than 10 -3 when the received signal powers of LP01, LP11a, LP11b, LP21a, LP21b, and LP02 are -37.84 dBm, -36.47 dBm, -36.20 dBm, -35.27 dBm, -35.37 dBm, and -35.79 dBm, respectively.
