Optical polarization beam combiner/splitter

   
   

An optical device for combining two orthogonally polarized beams or splitting a beam into two orthogonally polarized beams is provided that utilizes two collimating/focusing lenses and a thin film wire-grid polarizer. Because the thin film wire-grid polarizer can be fabricated in very thin profile, the provision of a thin film wire-grid polarizer allows the optical polarization beam combiner/splitter device to be highly integrated and simultaneously realize a number of performance advantages of a thin film wire-grid polarizer over other types of polarizers utilized in various prior art polarization beam combiner/splitters.
