Abstract

We propose miniaturizing polarizing beam splitters (PBS) with metamaterials. We use an inverse design approach that can optimize for the entire device compatible with 3D lithography. The devices operate with broadband beam deflection up to 45° and minimal dispersion in the mid wave infrared range of 4.3 µm to 4.7 µm.
