Abstract
A purpose of the present invention is to provide an optical frequency comb generator control device capable of obtaining a stable output by performing a control of a resonator length or a light source frequency such that a control point is located at a position where an optical frequency comb is generated most widely. A carrier frequency component of an optical frequency comb emitted from an optical resonator of an optical frequency comb generator as a transmitted light or a reflected light is attenuated by an optical filter, an optical frequency component extracted via the optical filter is received by a photodetectorto detect an optical intensity, and an optical resonant length of the optical resonator or a light source frequency of an incident light is feedback controlled by a resonance control unit by using a detection signal of the photodetector.
