ABSTRACT:
An asymmetric optical circulator has three ports: a first fiber optic port, a second free space port, and a third fiber optic port. Light entering the first port exits the second port, and light entering the second port exits the third port. However, the two fiber ports are not the same. Instead, the two optical fibers have different coupling characteristics.
