ABSTRACT:
An integratable optical isolator includes a polarizer, a non-reciprocal rotator, and a reciprocal rotator. The polarizer includes first and second ports. The polarizer is configured to receive a forward propagating wave at the first port and to output a polarized forward propagating wave having a first plane of polarization at the second port. The non-reciprocal rotator is coupled to receive the polarized forward propagating wave from the second port of the polarizer. The non-reciprocal rotator rotates the polarized forward propagating wave from the first plane of polarization to a second plane of polarization. The reciprocal rotator is coupled to the non-reciprocal rotator to receive the polarized forward propagating wave. The reciprocal rotator rotates the polarized forward propagating wave from the second plane of polarization back to the first plane of polarization.
