Abstract

An optical bypass switch receives arbitrarily polarized light from an input optical fiber which is divided into the P and S-polarized light beams by a polarization beamsplitter. These P and S-polarized light beams are focussed to a magneto-optic garnet wherein the plane of polarization is rotated in accordance with a desired switching function and directed to an output optical fiber determined by the polarization rotation state established in the magneto-optic garnet.
