| 摘 要： | 提出并验证了一种使用单光子载波、基于 IQ 调制和相干检测的新方法来传输两个矢量信号，单光子载波上的同一个偏振态光携带 IQ 调制信号，具有正交偏振状态的光载波直接通过光波调制光波传输，两个正交极化波的光发送到相干检测器中解调。仿真实验了在25 km 单模光纤两个 QPSK 信号以数据率为1 Gbps 传输时的传输性能。

| Abstract: | A novel approach to transmit two vector signals based on IQ modulation and coherent detection by using a single photon carrier is proposed and demonstrated.The same polarization state light of single photon carrier carries IQ modulation signal,and the optical carrier with an orthogonal polarization state directly modulated transmission of optical wave through the optical wave.At the receiver,the two orthogonally polarized light waves are separated and sent to a coherent detector.The performance of the transmission is evaluated when the transmission of two QPSK signals with a data rate of 1 Gbps is implemented over a 25 km single-mode fiber. |
