In this letter, we describe the impact of quadrature imbalance (QI) in the presence of frequency offset and phase drift ......

基于级联相位调制器(PM),设计并实现了一种梳线数量与梳线间距均可调谐的光学频率梳(OFC)产生方案。采用正弦型射频信号与其倍频信......

提出了一种简化的相干检测系统,通过在时域上交替探测信号的同向(I)及正交(Q)信息分量,实现了基于单个平衡光电探测器(BPD)的相位......

为了实现信号同相分量和正交分量的交替检测,提出了一种基于预设频率偏移的相干探测方案。该方案所需的硬件数量与外差检测一致,均......

A spectrum efficient OFDM scheme named Time Domain Synchronous-OFDM(TDS-OFDM)is introduced into coherent optical transmi......
