Abstract

A fiber optic faceplate fabricated using a series of stacked ribbon structures. Each ribbon structure comprises optical fiber segments that run from an input edge to an output edge with fixed input and output fiber-to-fiber spacing. Input and output edge spacers may be used to provide spacing between stacked ribbon structures. Ribbon structures may be provided individually or as one or more sheets of ribbon structures.

Claims (19)

1. A method for forming an optical converter comprising:

(a) forming a plurality of ribbon structures, each ribbon structure having a ribbon width defined by an input edge and an output edge and having a single row of side-by-side light pipe segments, each light pipe segment providing an optical path from an input at said input edge to an output at said output edge;

(b) successively stacking said ribbon structures atop one another to build up said optical converter as a stack of adjacent rows of said light pipe segments; and

wherein the step of stacking said ribbon structures comprises repeatedly folding said ribbon structure back upon itself to form adjacent, overlaid rows of said light pipe segments, thereby forming the optical converter having a depth determined by said ribbon width.

2. A method for forming an optical fiber faceplate comprising:

(a) forming a sheet comprising a plurality of ribbon structures, each ribbon structure having a ribbon width defined by an input edge and an output edge, by

(i) defining said input edge by positioning an input edge spacer, running in a length direction, and defining said output edge by positioning an output edge spacer, running in said length direction;

(ii) lining up, side-by-side in a single layer and generally in parallel to each other along said length direction, a plurality of optical fiber segments for directing light from said input edge to said output edge;

(iii) fixing an input spacing between said fiber segments at said input edge spacer and an output spacing between said fiber segments at said output edge spacer;

(iv) providing a separation gap between any two adjacent said ribbon structures on said sheet;

each said ribbon structure comprising thereby a single row of said optical fiber segments having said fixed input and output spacing;

(b) accordion-folding said sheet together, folding at said separation gap, thereby stacking successive said ribbon structures atop one another to build up said optical fiber faceplate as a stack of adjacent rows of said optical fiber segments having said fixed input and output spacing.

3. A method for forming an optical fiber faceplate comprising

(a) forming a ribbon structure having a ribbon width defined by an input edge and an output edge, by

(i) defining said input edge by positioning an input edge spacer, running in a length direction, and defining said output edge by positioning an output edge spacer, running in said length direction;

(ii) lining up, side-by-side in a single layer and generally in parallel to each other along said length direction, a plurality of optical fiber segments for directing light from said input edge to said output edge;

(iii) fixing an input spacing between said fiber segments at said input edge spacer and an output spacing between said fiber segments at said output edge spacer;

said ribbon structure comprising thereby a single row of said optical fiber segments having said fixed input and output spacing; and

(b) repeatedly folding said ribbon structure back upon itself to form adjacent, overlaid rows of said optical fiber segments, thereby forming the optical fiber faceplate having a depth determined by said ribbon width.
