Paper Abstract

We have designed a low-loss Polarization Independent All-Fiber Optical Circulator for use in bi-directional fiber optics communication systems which can effectively double the information carrying capacity of existing fiber optics communications connections. Previous designs based on bulk optics or planar waveguides have had limited utility because of their high losses (often higher than 2.5 dB) compared to a 3 dB directional coupler. While coupling between a bulk optics or a planar waveguide optical circulator and an optical fiber results in a large loss, our design reduces coupling losses by keeping the path of the signal within the fiber throughout the device. Because splice losses between fibers can be as low as 0.2 dB, elimination of large coupling losses give our design low overall losses. We are currently evaluating different implementation of our design.
