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
Optical Circulator
An optical circulator is defined as a nonreciprocal device that transmits light between ports in a predefined sequence, utilizing the Faraday effect to change the polarization of optical signals,
Faraday Circulators
Faraday circulators are magneto-optic devices based on the Faraday effect — rotation of the polarization — as explained in the article on Faraday rotators.
