OPTICAL WAVEGUIDE TYPE OPTICAL MODULATOR AND OPTICAL WAVEGUIDE TYPE OPTICAL FREQUENCY COMB GENERATOR

摘要

PROBLEM TO BE SOLVED: To efficiently generate an optical frequency comb. SOLUTION: An optical resonator 10 constituted by forming an incidence-end reflecting film 14A and a projection-end reflecting film 14B on two opposite end surfaces of an electrooptic crystal substrate 12 where an optical waveguide 11 passing beam light L1 causing optical resonance is formed is built in a cavity microwave resonator 20 surrounded with metal.
