ABSTRACT:
A reflective circulator includes a birefringent splitting and combining element, a non-reciprocal polarization rotator, and birefringent translating element. Some embodiments of the circulator include an inverting reflector. The circulator can be scaled to have a large number of ports arranged in a one dimensional array or in a two dimensional pattern, such as an array.
