Abstract

本申请实施例公开了一种跟踪光波长的装置，包括：滤波模块，用于接收未知波长的第一光信号，并对第一光信号作滤波处理得到两路第二光信号，并将该两路第二光信号输出至光电转换模块；光电转换模块，用于接收该两路第二光信号，并对该两路第二光信号作光电转换处理得到两路第一电信号，并将该两路第一电信号输出至控制模块；控制模块，用于接收该两路第一电信号，并根据该两路第一电信号调节滤波模块的工作参数，以使该两路第一电信号之间满足第一预设关系；调节工作参数后的滤波模块，还用于接收可调谐激光器输出的第三光信号，并对第三光信号作滤波处理后得到两路第四光信号，并将该两路第四光信号输出至光电转换模块；光电转换模块还用于接收该两路第四光信号，并对该两路第四光信号作光电转换处理得到两路第二电信号，并将该两路第二电信号输出至控制模块；控制模块还用于接收该两路第二电信号，并根据该两路第二电信号调节可调谐激光器的工作参数，以使该两路第二电信号之间满足第二预设关系，使得第三光信号的波长与第一光信号的波长对准。
