Abstract

An optical isolator comprising an optical isolator unit having a structure depending on a plane of polarization of incident light, a first optical system for splitting the incident light into two polarized components for incidence on the optical isolator unit, and a second optical system for combining the two polarized components emerging from the optical isolator unit. The optical isolator can thus manifest an excellent effect of isolation without considering the plane of polarization of the incident light.
