Abstract
An optical frequency comb generator includes an oscillator () for oscillating modulating signals of a preset frequency, and an optical resonator () formed by an incident side reflecting mirror () and an outgoing side reflecting mirror (), arranged parallel to each other. The optical resonator causes resonation in light incident via the incident side reflecting mirror (). The optical frequency comb generator also includes an optical phase modulation unit () arranged between the incident side reflecting mirror () and the outgoing side reflecting mirror () for phase modulating the light, resonated by the optical resonator (), by the modulating signals supplied from the oscillator (), and for generating a plurality of sidebands centered about the frequency of the incident light at a frequency interval of the modulating signal. The outgoing side reflecting mirror () sets the transmittance from one frequency to another responsive to the light intensity of the generated sidebands.
