Optical circulators route an optical signal from an input port to an output port in a non-reciprocal manner. For example, in a 3-port circulator a signal entering Port 1 will exit Port 2, a signal entering Port 2 will exit Port 3 and a signal entering Port 3 will exit Port 1. Circulators are available in 3- or 4-port configurations.
