Abstract
本申请实施例公开了一种处理电路、光模块以及啁啾检测方法，涉及光通信领域，能够快速准确地确定激光器的啁啾系数。具体方案为：一种处理电路，应用于光模块，光模块包括啁啾检测电路和光发射模块，处理电路包括：第一光耦合器，光延迟线，光滤波器，第二光耦合器。第一光耦合器接收来自光发射模块的光信号，对光信号进行分路处理，得到第一输出信号和第二输出信号。光延迟线对第一输出信号进行延迟处理，得到延迟信号。光滤波器对第二输出信号进行滤波处理，得到滤波信号。第二光耦合器对延迟信号以及滤波信号进行合路处理获得输出检测信号，并发送输出检测信号给啁啾检测电路，使啁啾检测电路根据输出检测信号，计算光发射模块的啁啾系数。
