ABSTRACT:
An optical isolator (2) comprising two polariser means (10,12), two input/output ports (4,6) formed respectively on the polariser means (10,12), and optical rotator means (14,18) disposed between the polariser means (10,12), the optical rotator means (14,18) including Faraday rotator means (14) and being selectively configured so the isolator (2) performs one of a plurality of isolator functions.
