Abstract
An optical communication system is disclosed comprising a transmission assembly including a semiconductor laser amplifier. The laser amplifier superimposes onto an amplitude modulated signal a phase modulation corresponding to the amplitude modulation. The optical communication system may further include a separation device for filtering out the amplitude modulation. A receiving assembly is provided for detecting the phase modulation of a transmitted signal.
