DEVICE FOR REGULATING A LASER DIODE

摘要

The present invention relates to a device for regulating a laser diode, which comprises a generator of a pilot frequency signal modulated by a reference signal forming part of a composite signal to be emitted and a gain regulator of the composite signal. The regulation circuit comprises a photodiode whose output signal is demodulated by means of the pilot frequency signal, filtered then detected before being applied to the gain regulator.
