We have been studying schemes to realize polarization insensitivity for Si wire waveguide wavelength filter required for optical telecommunications. Polarization diversity method is used in DWDM system. In this report we present a polarization converter and mode sorter Y-branch composite structure. A wide band and fabrication tolerance are attained.
