MULTIPLE RESONATOR TYPE OPTICAL FREQUENCY COMB GENERATOR

摘要

PROBLEM TO BE SOLVED: To provide a multiple resonator type optical frequency comb generator which secures a broad control band region and stably generates an optical frequency comb. SOLUTION: Since an LN crystal plate 120 for controlling resonator length is disposed between a monolithic optical resonator 110 and a movable mirror 130 which is moved by an electromechanical converting element 140, the control of resonator length by means of the movable mirror 130 and the control of resonator length by means of the LN crystal plate 120 are concurrently performed.
