Abstract :
We demonstrate bandwidth- and wavelength-tunable comb filters with sharp-cutoff and low-dispersion characteristics using a 16-tap PLC-based optical transversal filter. Such filters have no limitation of the wavelength-channel number owing to the cascaded Mach-Zehnder interferometer structure.
