Abstract
The performance, reliability, and cost of the optical couplers depends heavily on their design and packaging technologies. A need still exists in the art of design and manufacturing of optical coupler devices to provide superior performance, improved reliability and reduced cost simultaneously while addressing issues such as walk-off. Such improvements arising from the inclusion of asymmetric optical elements within the optical path rather than the circularly symmetric optical elements within the prior art.
