Abstract
The invention in the simplest form is a low-profile optical waveguide assembly for interfacing a two-dimensional optoelectronic array to standard fiber bundles. The present invention serves both to bend light and fan out light-carrying guides and to transition from the optoelectronic array pitch to an industry standard pitch for connectorization. There are several embodiments considered herein, however the preferred embodiments are for an optical waveguide assembly that includes a waveguide housing supporting a plurality of waveguide sheets, each sheet includes an array of waveguides feeding a plurality of industry standard ferrules.
Claims12
A system for the connection of optoelectronic arrays to optical cable, said system comprising:
- at least one two-dimensional optoelectronic array having a plurality of optoelectric devices arraigned in a compact geometery;
- a plurality of flexible waveguide sheets, having array and connector ends;
- a plurality of one-dimensional waveguides, having first and second ends, disposed within and coterminous with said waveguide sheets;
- said first end having a first pitch;
- said second end having a second pitch, wherein said second pitch differs from said first pitch;
- said first ends of said waveguides are disposed within said array ends of said waveguide sheets and are disposed so as to match said compact geometry of said devices within said array;
- and
- said second ends of said waveguides are disposed within said connector ends of said waveguide sheets and are disposed so as to mate with a connector having an industry standard geometry.
A low-profile optical assembly for interfacing a two-dimensional optoelectronic array to an optical connector, comprising:
- two or more flexible waveguide sheets, wherein each of said waveguide sheets has an array end and a connector end;
- a plurality of one-dimensional waveguides in each of said waveguide sheets, wherein each of said waveguides has an array end pitch at said any end and a connector end pitch at said connector end, and wherein said array end pitch matches a pitch of said optoelectronic array and said connector end pitch matches a pitch of said optical connector;
- and wherein said pitch of said optoelectronic array and said pitch of said optical connector are not equal;
- and a waveguide housing at said array end of said waveguide sheets for retaining said waveguide sheets, wherein each of said waveguide sheets has an array end spacing at said array end and a connector end spacing at said connector end, and wherein said array end spacing matches a spacing at said optoelectronic array and said connector end spacing matches a spacing at said optical connector.
