ABSTRACT:
The system of a variable lightwave functional apparatus comprising: an acousto-optical modulator for outputting wavelength multiplexed light containing a plurality of pulses having a first wavelength interval; a coupler arranged at an output of said acousto-optical modulator; a polarization branching/coupling device having a first port to a third port, for branching the output form said coupler, which is entered from said first port into the polarization branching/coupling device, to both said second port and said third port; an optical amplifier connected to said second port of said polarization branching/coupling device; and said variable lightwave functional circuit and arranged between said second port of said polarization branching/coupling device and said optical amplifier; wherein: multi-wavelength oscillation light is outputted from said coupler by laser light from said acousto-optical modulator.
