Abstract:
1. An optical coupler for conveying optical signals between an optical fiber and one or more optical signaling devices in said optical coupler, said coupler comprising an optical element to (i) direct optical signals from an electromagnetic radiation emitter as a said optical signaling device into an adjacent optical fiber along a transmission axis thereof for transmission through said optical fiber, and to (ii) receive optical signals from said optical fiber after transmission therethrough that are directed by said optical element to propagate away from an extension of said transmission axis past said optical fiber toward said emitter so as to substantially avoid impinging on said emitter, said emitter being provided in an optoelectronic signaling structure at a first portion of an optical signaling device surface in said structure with said structure having a substrate supporting remaining portions thereof, said optical signaling device surface first portion extending substantially laterally in said optoelectronic signaling structure with respect to said transmission axis extension and also having positioned thereabout an extended second portion of said optical signaling device surface at which an electromagnetic radiation detector as an optical signaling device is provided in said optoelectronic structure, said detector extending along at least a nonplanar portion of a peripheral side of said emitter to thereby receive said optical signals from said optical fiber that are directed thereto by said optical element.
