Optical circulator
An optical circulator is a three- or four-port optical device designed such that light entering any port exits from the next. This means that if light enters port 1 it is emitted from port 2, but if some of the emitted light is reflected back to the circulator, it does not come out of port 1 but instead exits from port 3. This is analogous to the operation of an electronic circulator. Fiber-optic circulators are used to separate optical signals
Faraday Circulators
A Faraday circulator is a non-reciprocal optical device, typically with three or four ports, that directs light sequentially from one port to the next in a single rotational
Optical Circulator
The operation principle of an optical circulator is based on the use of magneto-optic materials used as Faraday rotators that changes the polarization of the input signal at each port of the device (Hui, 2020).
What is an Optical Circulator and How Does it Work
