ABSTRACT:
An optical circulator in which non-reciprocal polarized light rotating means is disposed between first and second polarizing prisms, the non-reciprocal polarized light rotating means being composed of a Faraday rotator that the polarized light rotating angle, for example, by an external field is 45.degree. and compensating means of an optically active or anisotropic crystal that the polarized light rotating angle is 45.degree.. A light passing through the non-reciprocal polarized light rotating means in one direction is rotated through 90.degree. but a light passing through the non-reciprocal polarized light rotating means in a reverse direction is not rotated. Two input/output faces of each of the non-reciprocal polarized light rotating means and the first and second polarizing prisms, are optically coupled, and the remaining input/output faces of the first and second polarizing prisms, four in all, are used as first through fourth input/output ports, respectively.
