摘要	There are provided an optical transmitter and a method for transmitting an optical signal, which realizes an optimum desired temperature arrival time without changing a Peltier element size, a drive current and a drive voltage, and which is stabilized by control having a sufficient phase margin. Different loop filters for heating and cooling are provided for a control loop of the Peltier element on which a laser diode is mounted, and the respective appropriate loop filters are selected and used on the basis of heating or cooling information.
其他摘要	提供了一种光发射器和一种用于发送光信号的方法，其实现了最佳的期望温度到达时间而不改变珀耳帖元件尺寸，驱动电流和驱动电压，并且通过具有足够相位裕度的控制来稳定。用于加热和冷却的不同环路滤波器被提供用于其上安装有激光二极管的珀耳帖元件的控制回路，并且基于加热或冷却信息选择和使用相应的适当环路滤波器。
主权项	An optical transmitter, comprising: a temperature control circuit that increases or decreases a temperature of a laser diode mounted on a Peltier element on the basis of a characteristic of the laser diode, wherein a characteristic of a loop filter of the temperature control circuit is changed over according to a direction of a current that flows in the Peltier element.
