An integrated optical device for the separation/combination of orthogonal polarizations is described. The device relies on simultaneous symmetric and antisymmetric 1 x 1 off-center self-imaging. Calculations show that 90% throughput and 0.1% crosstalk can often be attained, with device length less than or comparable to other integrated optical polarization separation devices. The device is passive, requires only a single mask, and is not restricted to a specific fabrication method or material system. Devices can even be made in isotropic material systems with a deep etch. Simulation results are presented for the lithium niobate and glass waveguide material systems.
