Ultra-flat optical frequency comb signal generator

摘要

It is an object of the present invention to provide an optical frequency comb generator to generate an optical frequency comb with flat spectral properties using a single modulator. The optical frequency comb generator comprises: a drive signal system (11) and a bias signal system (14) for driving a first drive signal (9), a second drive signals (10), and bias signals (12,13) in accordance with the following Formula (I): ”A±”¸ = À/2 (I) (where ”A and ”¸ are defined, respectively, as ”A = (A 1 -A 2 )/2 and ”¸ = (¸ 1 -¸ 2 )/2, A 1 and A 2 indicate, respectively, optical phase shift amplitudes guided by the first drive signal and the second drive signal when input into the electrodes, and ¸ 1 and ¸ 2 indicate, respectively, the phases of the bias signals applied to the first waveguide and the second waveguide).
