ABSTRACT:
In a directly modulated optical module, the input current to drive the semiconductor laser is controlled so as to make a rate of change in fall time smaller than a rate of change in rise time (inclination) in order to improve the eye opening of an eye pattern and extend the transmission distance. In addition, the input current is overshot at least during the period of transient state following the rising edge.
