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 Isolators and Circulators

Development of a Low-Loss Optical Circulator
Figure 1 is a schematic diagram of the newly developed low-loss 3-port optical circulator. It comprises three single-mode fibers (SMFs), single-fiber ferrules, lenses and a non-reciprocal section using a
Device structure and resonant system a, Schematic of a circulator
Here, we present a scheme for a neuromorphic system that relies on linear wave scattering and yet achieves non-linear processing with a high expressivity. The key idea is to inject the input via...
Faraday Circulators
Typically, a circulator has three or four optical ports (inputs / outputs), although there could in principle be more. Light entering one port exits from the next port, or from the first port if injected into the last.
Optical Circulator
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
