ABSTRACT:
In an optical communication system, wherein light intensity modulation with no carrier is performed using a light emitting diode with linear relation of the drive signal current vs. optical output power over a range which changes with frequency of the drive signal, the input signal is modulated for relatively larger amplification of frequencies higher than a predetermined frequency, above the thermal response frequency of the light emitting diode, than for frequencies lower than the predetermined frequency.
