ABSTRACT:
A three port optical wave circulator, comprising a cylindrical structure made of magneto-optic material which is optically anisotropic in a biasing magnetic field, for selectably transmitting a light beam incident to a port on the cylinder surface in a direction plus or minus 120.degree. from the incident direction. In the presence of a selected biasing magnetic field, a light beam incident to any port of the circulator is uniformly transmitted in the selected direction to a second port.
