Abstract

Polarization components play a vital role in a variety of consumer products, including displays, AR/VR devices, sensors including LIDAR, as well as in modern photonics systems. Traditional polarizing beam splitters based on birefringent crystals are too bulky and expensive for mass production. Multi-layer polarizing beam-splitting structures are limited to the transparency window of the substrate and the layer stack and often have low radiation resistance. Plasmonic structures, such as wire grid polarizers, are often the only viable choice in the infrared (IR). Multi-layer polarizing beam splitters and wire grid polarizers require folded configurations for their integration into photonics systems. This work provides design and performance optimization details of meta-optics all-dielectric polarization beam splitters for the IR spectral region operating in transmission for both polarization states. Their performance is compared to that of wire grid polarizers designed for the same spectral range, and practical considerations for their manufacturability and system integration are also presented.
