Hexahedral polarizing beamsplitter

Abstract:

A hexahedral polarization beamsplitter is constructed with four substantially triangular prisms with a polarizing beamsplitter located within each of the interfaces between the assembled prisms. An input side of the assembly receives an unpolarized beam and two opposing output sides of the assembly transmit orthogonally polarized portions of the unpolarized beam in opposite directions. The polarizing beamsplitters are arranged at the interfaces so that each of the orthogonally polarized portions of the unpolarized beam is both reflected by one of the polarizing beamsplitters and transmitted by another of the polarizing beamsplitters.
