ABSTRACT:
A high performance optical circulator is formed by a polarization beam splitter and optical port assemblies. The polarization beam splitter is formed by two prisms with an interface between the prisms. The interface transmits linearly polarized light directed at the interface in directions responsive to a polarization orientation of linearly polarized light. The optical port assemblies are arranged with respect to the polarization beam splitter so that light from one port assembly is transmitted by the polarization beam splitter interface to another optical port assembly and light from this optical port assembly is transmitted by the beam splitter interface to still another optical port assembly.
