Abstract
A photonic device has a polarization-dependent region and a device layer including a first cladding film, a second cladding film, and a core film. The core film includes one of (1) a material having an index nand (2) alternating layers of a first material having a first index and second material having a second index. The alternating layers have an effective index for TE polarized light nand an effective index for TM polarized light n. Each of the first cladding film and the second cladding film include the other of (1) the material having the index of refraction nand (2) the alternating layers n<n<n, and the indices of the upper cladding and the lower cladding are less than n, nand n. A polarizer, polarizing beam splitter and coupler using clipped coupling can employ the material having an index nand the alternating layers.
