SUPER FLAT OPTICAL FREQUENCY COM SIGNAL GENERATOR

摘要

An optical frequency COM generator generating an optical frequency COM having flat spectrum characteristics using a single modulator. The optical frequency COM generator has a drive signal system (11) and a bias signal system (14) which drive a first drive signal (9), a second drive signal (10) and bias signals (12, 13) to satisfy the following expression (I). ” A+” ¸=À/2 (I). (where, ” A and ” ¸ are defined as ”A‰¡(A 1 -A 2 )/2 and ”¸ ‰¡(¸ 1 -¸ 2 )/2, respectively, A 1 and A 2 represent the amplitudes of the first and second drive signals when they are inputted to the electrodes of the first and second drive signals, respectively, and ¸ 1 and ¸ 2 represent the phases of bias voltages applied to first and second waveguides, respectively.)
