Optical waveguide evanescent ribbon coupler
First Claim
1. An evanescent optically coupled electronic device comprising:
- A) a backplane wave guide or mother board comprising a set of parallel carriers that define a first plurality of parallel channels and include a first array of optical fibers having exposed cores in said first plurality of parallel channels;
B) at least one electronic card or daughter board including a high speed optical waveguide bus;
C) a flexible fiber ribbon or film including waveguides comprising individual optical fibers of locally increased refractive index joined by a web of suitable material forming said high speed optical waveguide bus and optically connecting said backplane waveguide and said at least one electronic card with no 90°
angle turns; and
D) a mechanism for retaining said first array of optical fibers having exposed cores in abutting and facing evanescent optical contact with said individual optical fibers in said flexible fiber or ribbon.

Abstract
An evanescent optically coupled electronic device including: a backplane wave guide or mother board including a set of parallel carriers that define a first plurality of parallel channels and include a first array of optical fibers having exposed cores in the first plurality of parallel channels; at least one electronic card or daughter board including a high speed optical waveguide bus; a flexible fiber ribbon or film including waveguides made up of individual optical fibers of locally increased refractive index joined by a web of suitable material forming the high speed optical waveguide bus and optically connecting the backplane waveguide and the at least one electronic card with no 90° angle turns; and a mechanism for retaining the first array of optical fibers having exposed cores in abutting and facing evanescent optical contact with the individual optical fibers in the flexible fiber or ribbon.
