Abstract :
Wavelength characteristics of the extinction ratio of optical Mach-Zehnder modulator using an active Y-branch is evaluated over C-band wavelengths. The observed extinction ratios are achieved greater than 60 dB at all of the wavelengths by optimization of applying voltage to the Y-branch by each wavelength.
