ABSTRACT:
A multi-stage optical isolating device having at least three stages includes birefringent crystals for separating shifting and combining an incoming beam of light into orthogonal polarized beams. The multi-stage device also includes at least three Faraday rotators that rotate incoming light propagating through the device in a same direction. The inclusion of a reciprocal rotator in the form of a half-wave plate advantageously obviates orienting the Faraday rotators differently.
