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

Because of their high isolation of the input and reflected optical powers and their low insertion loss, optical circulators are widely used in advanced fiber-optic communications and fiber-optic sensor

Optical circulators operate based on Faraday rotation and polarization control. Inside the device, a magneto-optic crystal (commonly TGG – Terbium Gallium Garnet) and polarizing

Unlike isolators, which simply block backward reflections, circulators enable bidirectional communication by directing light from Port 1 → Port 2, Port 2 → Port 3, and so on, while maintaining

A basic optical circulator is a three-terminal device as illustrated in Figure 3.5.26, where terminal 1 is the input port and terminal 2 is the output port, while the reflected signal back into terminal 2 will be

Fiber optic circulators act as signal routers, transmitting light from an input fiber to an output fiber, but directing light that returns along that output fiber to a third port.

The 3-port optical circulator is a multi-port non-mutual-easy optical device, and light can only travel in one direction.

Thorlabs'' Optical Circulators are non-reciprocating, one-directional, three port devices which are great for bidirectional propagation of light in a single fiber.

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 direction (e.g., 1 → 2, 2 → 3, and 3 → 1).
