Optical isolator core is a combination of a polarization beam splitter cube (PBS) and a quarter wave-plate made of crystal quartz. Incident light is linearly polarized by PBS and converted to circular polarization by the quarter wave-plate. If any portion of the emerging beam is reflected back into the isolator, the quarter wave-plate will convert the reflected beam into a linearly polarized beam which is perpendicular to the input beam. This beam is then blocked by PBS and it will not return to the input side of the system.
