Abstract
A polarization-sensitive photonic splitter may include a lower cladding layer and a device layer formed from a first waveguide supporting TE and TM light, a second waveguide, a third waveguide, and a transition core. The first waveguide core and the second waveguide core are formed from one of a first core structure or a second core structure, and the third waveguide is formed from the other structure. The first core structure has an index of refraction n. The second core structure is formed as alternating layers providing an effective index of refraction for TE light nand an effective index of refraction for TM light n, where n<n<n. The transition core is formed from the first core structure adjacent to the second core structure and is coupled to the first transition core at one and the second and third transition cores at the other end.
