Abstract

Apparatus and methods for a polarization converter comprising a polarization beam splitter for receiving an input light beam and allows a transverse magnetic to pass through the polarization beam splitter and reflects a transverse electric wave and a diffraction grating having a reflectivity and polarization convertible grating for receiving the transverse electric wave reflects back a reflected transverse electric wave having a polarization rotation. The broadband wide-angle polarization beam splitter can be alternative optical elements such as a prism or an optical device having multi-layered films. The diffraction grating can be a diffraction grating having alternating parallel protrusions and recesses, metallic diffraction grating, metal-coated diffraction grating, metal-coated multi-layered diffraction grating, non-metallic reflective material surface grating, volume grating, a multi-layer grating, diffractive grating having sub-wavelength grating periods or diffractive grating ha
