摘要	A light source mode alignment device and method and a passive optical network system are provided. The device includes a laser and a temperature control unit connected to each other and further includes a signal processing unit. The laser converts an incident light into a current signal. The current signal is amplified and converted into a voltage signal via a transimpedance amplifier. Together with a modulation signal generated by the signal processing unit, the voltage signal adjusts a bias voltage of the temperature control unit.
其他摘要	提供了一种光源模式对准装置和方法以及无源光网络系统。该装置包括彼此连接的激光器和温度控制单元，并且还包括信号处理单元。激光器将入射光转换成电流信号。电流信号被放大并通过跨阻抗放大器转换成电压信号。与信号处理单元产生的调制信号一起，电压信号调节温度控制单元的偏置电压。
