Abstract
An optical filter may include a substrate. The optical filter may include a set of alternating high refractive index layers and low refractive index layers disposed onto the substrate to polarization beam split incident light. The set of alternating high refractive index layers and low refractive index may layers may be disposed such that a first polarization of the incident light with a spectral range of less than approximately 800 nanometers (nm) is reflected by the optical filter and a second polarization of the incident light with a spectral range of greater than approximately 800 nm is passed through by the optical filter. The high refractive index layers may be hydrogenated silicon (Si:H). The low refractive index layers may be silicon dioxide (SiO).
