A mode-evolution-based polarization splitter suitable for high-index-contrast systems and directly integratable with a recently reported on-polarization rotator is described and its performance verified through both finite-difference time-domain and eigenmode expansion simulations. For a device length of 200 µm, greater than 22 dB of extinction is obtained across a 1.45-1.75-µm bandwidth.
