Paper Abstract

We introduce a novel polarizing beam splitter that uses the anisotropic spectral reflectivity (ASR) characteristics of a high spatial frequency multilayer binary grating. By combining the form birefringence effect of a high spatial frequency grating with the resonant reflectivity of a periodic multilayer structure, the ASR characteristics for the two orthogonal linear polarizations are obtained. Such ASR effects allow us to design an optical element that is transparent for TM polarization but reflective for TE polarization. The properties of the polarizing beam splitter are investigated using rigorous coupled-wave analysis. The design results show that an ASR polarization beam splitter can provide a high polarization extinction ratio for optical waves from a wide range of incident angles and a broad optical spectral bandwidth. Such ASR polarizing beam splitters are uniquely suitable for image processing and optical interconnection applications.
