Optical transmitter and method for transmitting optical signal |
摘要 |
<p>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. <IMAGE></p> |
