    Abstract: An improved waveguide structure employing blocks of waveguide core material positioned sufficiently close to a waveguide core thereby eliminating strain effects and its resulting undesirable polarization crosstalk. The improved structures are applicable to a variety of optical components including bent waveguides, directional and star couplers.

    Abstract: A low-loss rectangular-passband multiplexer including a three-arm interferometer coherently connected to a waveguide grating router (WGR), resulting in a passband substantially of type N=3, without intrinsic loss. The three-arm interferometer has a free-spectral range (FSR) substantially equal to the channel spacing and is connected to an M-arm interferometer having a much larger FSR. The three-arm interferometer includes three waveguides each exhibiting a linearly increasing path length optically connected to a 1×3 coupler and a 3×3 coupler. The 1×3 coupler may be constructed from a series of Y-branch couplers.
