Abstract:
    Provided is an optical circuit element and, particularly, an optical circulator or the like, that exhibits an excellent extinction ratio and that can be easily produced at a decreased cost. An optical circuit element comprising, in combination, two polarized light-separating elements, two totally reflecting mirrors, at least a piece of polarizing plane rotating element independent of a direction of travel of light, at least a piece of polarizing plane rotating element dependent of a direction of travel of light, a plurality of light incident/outgoing ports, and a magnetic field application means, wherein said polarized light-separating elements and said totally reflecting mirrors are formed of the same or different multi-layer polymer films.
