Abstract:
An apparatus of polarization self-compensated delay line interferometer. The apparatus includes a first waveguide arm of a first material of a first length disposed between an input coupler and an output coupler and a second waveguide arm of the first material of a second length different from the first length disposed between the same input coupler and the same output coupler. The apparatus produces an interference spectrum with multiple periodic passband peaks where certain TE (transverse electric) and TM (transverse magnetic) polarization mode passpand peaks are lined up. The apparatus further includes a section of waveguide of a birefringence material of a third length added to the second waveguide arm to induce a phase shift of the lined-up TE/TM passband peaks to a designated grid as corresponding polarization compensated channels of a wide optical band.

Claim (Index 1):
A delay line interferometer comprising:\n a first waveguide arm; a second waveguide arm being different from the first waveguide arm by a first length; a birefringence waveguide section of a second length inserted in the second waveguide arm; wherein the second length is varied stepwisely with a predetermined increment to induce sufficient number of phase shifts of an interference output spectrum with a number of passbank peaks for TE (transverse electric) polarization mode and TM (transverse magnetic) polarization mode being respectively lined up with the same number of channels of a designated optical band; wherein the first waveguide arm comprises a material selected from silicon nitride and silicon nitride mixed with silicon oxide.
