Abstract :
A waveguide with slanted sidewall is used to convert the fundamental TM mode to 1st order TE mode. The fundamental TE mode is unchanged. The two polarizations are converted to different order modes with the same polarization. Polarization independent wavelength filtering can be attained using this mode converter with AWG or devices which operates only for the TE mode.
