Abstract
A system and related method and assembly are disclosed. The system comprises one or more optical fibers configured to propagate one or more optical signals. The system further comprises at least a first cylindrical lens element fixedly connected with the one or more optical fibers and configured to expand the one or more optical signals along a predefined dimension. The system further comprises at least a second cylindrical lens element optically coupled with the first cylindrical lens element and configured to condense the expanded one or more optical signals along the predefined dimension.

A system comprising:
- one or more optical fibers configured to propagate one or more optical signals;
- at least a first cylindrical lens element fixedly connected with the one or more optical fibers and configured to expand the one or more optical signals along a predefined dimension;
- at least a second cylindrical lens element optically coupled with the first cylindrical lens element and configured to condense the expanded one or more optical signals along the predefined dimension;
- and
- one or more optical waveguides optically coupled with the second cylindrical lens element and configured to receive the condensed one or more optical signals,
- wherein the one or more optical waveguides are formed in a first substrate, and
- wherein the second cylindrical lens element is formed in a facet of the first substrate.
A method comprising:
- fixedly connecting at least a first cylindrical lens element with one or more optical fibers to produce an assembly, wherein the one or more optical fibers are configured to propagate one or more optical signals, wherein the first cylindrical lens element is configured to expand the one or more optical signals along a predefined dimension;
- and
- arranging the assembly relative to a substrate such that at least a second cylindrical lens element formed in a facet of the substrate is optically coupled with the first cylindrical lens element, wherein the second cylindrical lens element is configured to condense the expanded one or more optical signals along the predefined dimension,
- wherein one or more optical waveguides are formed in the substrate and configured to receive the condensed one or more optical signals.
An assembly comprising:
- a plurality of optical fibers each extending along a respective first axis and configured to propagate a respective optical signal, wherein the plurality of optical fibers are arranged in a substantially linear arrangement along a second axis that is substantially perpendicular to the respective first axes;
- and
- a single cylindrical lens element fixedly connected with a facet of the plurality of optical fibers and configured to expand the respective optical signals along a predefined dimension.
