Fiber optic ring resonator, a multi port optical device with non reciprocal characteristics. When an optical signal is input from any port, it can be output from the next port in the specified numerical order with minimal loss, while the loss from that port to all other ports is significant, making it a non communicating port.
Yuehai Technology develops and produces various packaging sizes and power circulators with high isolation characteristics.
