Polarization Maintaining Circulator

SiCART's PM Circulator is a three-port device that allows light to propagate in only one direction. A signal input from port 1 will be output from port 2 with minimal loss; a signal input from port 2 will be output from port 3 with minimal loss. Light input from port 2 experiences significant loss at port 1, and light input from port 3 experiences significant loss at both ports 2 and 1. The optical circulator is a non-reciprocal device, meaning that any property change caused by light passing th
