A low-loss and broadband all-fiber acousto-optic circulator
These circulators are electrically actuated and feature low insertion loss (0.81 dB), high extinction ratio up to 27 dB, and a broad bandwidth of at least 50 GHz. Furthermore, being fabricated
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

Low-loss and broadband all-fiber acousto-optic circulator
Here, we present a solution to this issue by realizing low-loss (0.81 dB), broadband (at least 50-GHz bandwidth), and high-extinction (up to 27 dB) circulators, based on Mach-Zehnder
Optical Circulator
However, these devices have very stringent specifications on optical attenuation, isolation, and polarization-dependent loss, so accurate measurements of these parameters are especially important.
Optical Circulator
An optical circulator is another device that is based on the nonreciprocal polarization of an optical signal by Faraday effect. A basic optical circulator is a three-terminal device as illustrated in Figure 3.5.26,
