ABSTRACT:
In a system in which a light emitting element such as a semiconductor laser, light emitting diode or the like is modulated directly by a drive current corresponding to an input modulation signal, the drive current is selected to correspond to an integrated value of the input modulation signal, thereby compensating for deterioration of the modulation characteristic based on a thermal effect in the light emitting element to obtain a desired optical output waveform.
