What is Optical Circulator and its Applications? – Fosco .

In a quasi-three-port circulator, light passes through from port 1 to port 2 and port 2 to port 3, but any light from port 3 is lost and cannot be propagated back to port 1. In most applications only a quasi-circulator is required. The operation of optical circulators is based on two main principles.
