ABSTRACT:
An optical component for use in optical devices, such as an interferometer fiber optic gyroscope including a polarizing beamsplitter and a non-reciprocal optical device mounted on a common substrate; and an optical transceiver. The optical component may be used in a low loss configuration with an optical source and a photodetector and associated focusing lenses and a fiber optic ring or coil sensor for a gyroscope. The non-reciprocal device rotates the polarization plane of light. transmitted from the source through the beamsplitter to the sensor, and light returned from the sensor toward the beamsplitter, by 45 degrees in the same direction so that substantially all return light incident on the beamsplitter is reflected toward the photodetector.
