Patent ID: 7083337

Claim:
In an optical communication system, an optical transceiver for coupling light from a source optical element to a receiving optical element, the optical transceiver comprising: a body including a source guide that connects the optical transceiver with the source optical element and a fiber guide that connects the optical transceiver with the receiving optical element; and a lens formed as a molded part of the body and that focuses light from the source optical element on a surface of the receiving optical element, wherein the lens aberrates light from the source optical element on the receiving optical element within an envelope defined on the receiving optical element to permit coupling of the aberrated light with the receiving optical element while reducing feedback reflected back to the source optical element, the lens comprising: a focusing lens surface that is positioned within a source guide such that far field radiation emitted by the source optical element is directed to the receiving optical element, the focusing lens surface having a curvature that introduces aberrations into the light focused on the receiving optical element; and a flat lens surface positioned within the fiber guide, wherein the flat lens surface does not have optical power.
