一种光模块
摘要：
本发明公开了一种光模块，主要包括：第一热电制冷TEC，所述第一TEC设置在所述激光器内部，所述第一TEC用于根据微程序控制器MCU输入开启信号进行加热或者制冷；第二TEC，所述第二TEC设置在所述激光器的外壳上，所述第二TEC用于根据所述MCU输入开启信号进行加热或者制冷；所述MCU用于根据激光器芯片驱动电路向所述激光器芯片输入的工作电流大小，确定向第一TEC以及第二TEC输入开启或者关闭信号。采用该方法，能够维持光模块的工作温度维持在恒定范围内，从而避免引起光模块工作失效。
摘要（英）：

An optical module includes: a first thermoelectric cooler (TEC) disposed at least partially inside a laser, a second TEC is disposed on a housing of the laser, and a micro control unit (MCU). The first TEC is configured to perform heating or cooling according to an enabling signal input by a MCU. The second TEC is configured to perform heating or cooling according to an enabling signal input by the MCU. The MCU is configured to determine whether to input an enabling signal or a disabling signal to the first TEC and the second TEC according to a size of operating current input by a drive circuit of a laser chip to the laser chip.
