MULTIPLE WAVELENGTH LIGHT SOURCE, AND GENERATION METHOD FOR MULTIPLE WAVELENGTH LIGHT

摘要

A multiple wavelength light source capable of generating a light with a larger number of wavelengths, and a generation method for a multiple wavelength light using the multiple wavelength light source. The multiple wavelength light source comprises an optical comb generator for obtaining an input light and a light group each element of which being deviated from the input light by a specified frequency, and a light regulator for regulating a light input to the optical comb generator, wherein the optical comb generator is constituted of an optical fiber loop (105) provided with an optical SSB modulator (101), an optical amplifier (102) for compensating for a modulation loss at the optical SSB modulator, a light input port (103) for receiving a light from the light source, and a light output port (104) for outputting a light, and the light regulator obtains a plurality of lights with different wavelengths.
