Compact optical fiber splitters

摘要

An apparatus includes one or more optical waveguides, one or more first micro-lenses, and one or more second micro-lenses. The one or more optical waveguides are formed in a substrate and are configured to convey respective optical signals between first ends and second ends of the optical waveguides. The one or more first micro-lenses are disposed on the respective first ends of the optical waveguides and are configured to couple the optical signals between the first ends and respective first optical elements. The one or more second micro-lenses are disposed on the respective second ends of the optical waveguides and are configured to couple the optical signals between the second ends and respective second optical elements.

1. An optical interconnect to direct optical signals between first and second ferrules of optical fibers, comprising:
a substrate; a first optical interface, configured to connect to the first ferrule of optical fibers, located on a first face of the substrate; a second optical interface, configured to connect to the second ferrule of optical fibers, located on a second face of the substrate; a plurality of optical waveguides, which are formed in the substrate and are configured to convey respective optical signals between the first optical interface and the second optical interface; one or more first micro-lenses, which are disposed on respective first ends of the optical waveguides and are configured to couple the optical signals between the first ends and the first ferrule; and one or more second micro-lenses, which are disposed on respective second ends of the optical waveguides and are configured to couple the optical signals between the second ends and the second ferrule, wherein each of the plurality of waveguides includes at least one horizontal bend and wherein the at least one horizontal bends of the plurality of waveguides are included in a single plane.
