Fiber Polarization Insensitive Circulator

The optical circulator is a three-port device, and light can only propagate in one direction. If a signal is input from port 1, it will be output from port 2; if a signal is input from port 2, it will be output from port 3, and the output loss is very small. When light is input from port 2, the loss when output from port 1 is large. Similarly, when light is input from port 3, the loss when output from ports 1 and 2 is also large. Optical circulators are non-reciprocal optical devices. Due to its high isolation and low insertion loss, fiber optic circulators are widely used in advanced communication systems.
