Abstract

本发明适用于光通信领域，提供了一种含多子波带的超通道的外差光信号接收系统和光信号接收方法，所述系统包括：循环阵列波导光栅、光电探测器、RFMix、ADC、OFDM接收机。本发明实施例，通过包含多个输入输出端口的循环阵列波导光栅对接收的包含多个相邻子波带的超通道信号和包含多个频率的本地光梳线信号进行光解复用，在循环阵列波导光栅的每个输出端口输出一个超通道信号的子波带信号和一个频率的本地光梳线信号，并通过光电探测器、RFMix和ADC对循环阵列波导光栅输出的信号进行转化，最终将转换的数字信号传输到OFDM接收机，使得包含多子波带的超通道信号和包含多频率的本地光梳线信号只需要一个光解复用器，简化了接收机的设计和成本。
