A study on the performance of a diode laser drive circuit

الملخص EN

A suitable drive circuit for a diode laser (670nm) was designed and constructed.

The drive current was designed according to the specification of a real optical fiber communication system.

The performance of the constructed drive circuit was tested.

The effect of temperature on the output optical power of the diode laser was investigated.

The temperature is varied from 15C-30C- five degrees for each step.

The optimum threshold drive current was detected at 15C.
