Abstract
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 () and a bias signal system () which drive a first drive signal (), a second drive signal () and bias signals () to satisfy the following expression (I). ΔA+Δθ=π/2 (I). (where, ΔA and Δθ are defined as ΔA≡(A−A)/2 and Δθ≡(θ−θ)/2, respectively, Aand Arepresent 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 θand θrepresent the phases of bias voltages applied to first and second waveguides, respectively.)
