Tailaert, D, Chong, H, Borel, P I, Frandsen, L H , De La Rue, R M and Baets, R (2003) A compact two-dimenstional grating coupler used as a polarization splitter. IEEE Photonics Technology Letters, 15, (9), 1249-1251.
We demonstrate a novel polarization splitter based on a two-dimensional grating etched in a silicon-on-insulator waveguide. The device couples orthogonal modes from a single-mode optical fiber into identical modes of two planar ridge waveguides. The extinction ratio is better than 18 dB in the wavelength range of 1530-1560 nm and the coupling efficiency is approximately 20%. The device is very compact and couples light only to transverse-electric modes of the planar waveguides. Therefore, it may be used in a polarization diversity configuration to implement a polarization insensitive photonic integrated circuit based on photonic crystal waveguides.
