摘要: Disclosed herein is a laser diode module having a thermoelectric cooling element, a laser diode, and a thermistor in a housing. The thermoelectric cooling element has a first surface and a second surface between which heat exchange is performed. The first surface is in close contact with an inner surface of the housing. A base is provided on the second surface in close contact therewith. A laser carrier and a thermistor carrier are provided on the base in close contact therewith. The laser diode and the thermistor are provided on the laser carrier and the thermistor carrier in close contact therewith, respectively. A portion of the base in the vicinity of the laser carrier is thermally connected to the housing by a metal plate, for example, thereby allowing high-precision temperature control of the laser diode.

摘要: 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.
