Abstract:

An optical device includes a polarization section having a port, the polarization section being for receiving light at the port and for outputting light at the port with a state of polarization orthoconjugate to the light received at the port. The polarization section includes a reflector, a bidirectional nonreciprocal rotator and a bidirectional polarizer. The bidirectional nonreciprocal rotator has first and second ends, the first end being operatively coupled to the port. The bidirectional polarizer has first and second ends, the first polarizer end being operatively coupled to the reflector and the second polarizer end being operatively coupled to the second rotator end. The optical device further includes an amplifying section having a port and a rotator-reflector, the amplifying section being for receiving light at the amplifying section port and for outputting light at the amplifying section port with a state of polarization orthoconjugate to the light received at the amplifying section port and being amplified with respect thereto. The optical device includes means for transmitting light in both directions between the polarization section port and the amplifying section port, and means responsive to light internal to the polarization section for outputting coherent light having stable and known state of polarization.
