Paper Abstract

We propose a novel broadband polarizing beam splitter with an embedded metal-wire nanograting structure that the metal wire is deposited in the grating trenches. This embedded structure makes the grating more firms in its applications. The design is based on Effective Medium Theory (EMT) and the structure is optimized with Rigorous Coupled Wave Theory (RCWA). The design results show that the polarizing beam splitter has uniform performance with wide variations in the angle of incidence and has low insertion loss, high polarization extinction ratio in a broad spectral range.
