摘要:
An optical module with a function to monitor a temperature within the package without installing any specific temperature sensing device is disclosed. The optical module of the invention includes an LD and a monitor PD in a CAN type housing. When the LD is inactive or driven under a constant bias current, the monitor PD receives a constant current independent of the temperature. The forward voltage of the monitor PD indicates the temperature within the package.
