Abstract
The present invention provides an optical interconnection device whereby arrays of fibers or waveguides arranged in a given orientation at an input side are rearranged in a three-dimensional rearrangement area within the device and exit at an output side arranged in a different orientation from the input side. Distinct arrays are created at the output side via manual or automated placement based on a roadmap.
Claims9
An optical rearrangement device comprising:
- an input side including at least first, second and third separate, flexible input light guide arrays, each of the arrays including a plurality of light guides,
- an output side in which the light guides of the at least first and second input light guide arrays are repositioned to form at least first and second separate, flexible output light guide arrays with a first one of the light guides of the first input light guide array being repositioned to extend into the first output light guide array, a second one of the light guides of the first input light guide array being repositioned to extend into the second output light guide array, and a first one of the light guides of the second input light guide array being repositioned to extend into the first output light guide array and a second one of the light guides of the second input light guide array being repositioned to extend into the second output light guide array, and a light guide of the third input light guide array being repositioned to extend into one of the output light guide arrays,
- an enclosure having an input opening and an output opening from which the input and output light guide arrays extend located between the input side and the output side which contains a non-planar, three-dimensional rearrangement area having a thickness defined by at least three light guides that cross over one another at approximately the same point as the light guides are repositioned, and
- an adhesive located in the enclosure to hold the light guide arrays in position in the rearrangement area.

A method of rearranging a plurality of optical waveguides comprising the steps of:
- arranging a plurality of optical wave guides into at least first, second and third separate, flexible input wave guide arrays at an input side;
- rearranging the plurality of optical wave guides in a three-dimensional rearrangement area to form at least first and second separate, flexible output arrays at an output side by repositioning at least a first one of the light guides of the first input light guide array to extend into the first output light guide array, repositioning a second one of the light guides of the first input light guide array to extend into the second output light guide array, repositioning a first one of the light guides of the second input light guide array to extend into the first output light guide array, repositioning a second one of the light guides of the second input light guide array to extend into the second output light guide array, and repositioning a light guide of the third input light guide array to extend into one of the output light guide arrays, the rearrangement area having a thickness defined by at least three light guides that cross over one another at approximately the same point as the light guides are repositioned;
- enclosing the rearrangement area in a housing having an input opening and an output opening from which input light guide arrays and output light guide arrays respectively extend;
- and
- holding the optical waveguides stably in position in the rearrangement area.
