Abstract

We report the design for the polarization independent Mach-Zehnder interferometer wavelength filter using sub-micron Si waveguide. The same waveguide cross sections can be used for the directional coupler and phase shifter. A high refractive index upper cladding structure enables an easy integration of the filter device and spot size converter. Optimized ridge waveguide also shows polarization independence.
