Abstract
A cube polarizing beam splitter (PBS) can have one or more of the following characteristics: high contrast (Tp/Ts), acceptance of a large range of incident angles, broadband, and symmetry. The cube PBS can include a pair of wire-grid polarizers sandwiched between a first prism and a second prism. There can be a boundary layer between the wire-grid polarizers. An optical path length of a transmitted beam can be equal or very close to an optical path length of a reflected beam.
