Polarization-Insensitive and Tunable Silicon Mach–Zehnder Wavelength Filters With Flat Transmission Passband
In this paper, an integrated polarization-insensitive optical comb filter with flat passband and tunable central wavelength is designed based on cascaded Mach–Zehnder structure. It is realized by employing three specific directional couplers with square waveguides. The central wavelength...
