Abstract

一种发射机以及用于发射光信号的方法，该发射机(200)包括：第一激光器(210)、N个第一FP激光器(220)、N个第一光信号检测单元(230)和N个第一调节单元(240)，其中，该第一激光器(210)用于发射第一光信号；每个该第一FP激光器(220)用于接收该第一光信号，并根据该第一光信号发射第一激发光信号；每个该第一光信号检测单元(230)用于检测相对应的第一FP激光器(220)发射的第一激发光信号，并且根据检测结果，确定该相对应的第一FP激光器(220)是否工作在注入锁定状态优化区间；每个该第一调节单元(240)用于若相对应的第一FP激光器(220)未工作在注入锁定状态优化区间，调节该相对应的第一FP激光器(220)的当前工作参数。该发射机能够发射具有较小色散代价的光信号。
