Abstract
Abstract A system for depositing and definitely positioning optical fibers on a base material. The process includes depositing a cladding base on a plastic tape by radio frequency triode sputtering. A slitted mask is placed over the cladded tape and fiber core material is sputtered onto the cladded surface in a controlled manner to form strips of fiber cores on the cladded base.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
127 words
A process for depositing and positioning optical fiber cores onto a base tape in a predetermined manner, comprising: evacuating a vacuum enclosure; filling said enclosure with an inert gas; forming an ionized plasma within said enclosure; positioning a supply of cladding material in a target position; energizing a tape feed to pass plastic tape over a deposition position; actuating a control means to cause sputtering of said cladding material onto said plastic tape; removing said cladding material supply from said target position; positioning a supply of fiber core material in said target position; placing an interruption mask over said deposition position, and re-energizing said tape feed and said control means to cause sputtering of said fiber core material through said interruption mask onto a cladded plastic tape.
Claim 2
Dependent Claim
127 words
A process for depositing and positioning optical fiber cores onto a base tape in a predetermined manner, comprising: evacuating a vacuum enclosure; filling said enclosure with an inert gas; forming an ionized plasma within said enclosure; positioning a supply of cladding material in a target position; energizing a tape feed to pass plastic tape over a deposition position; actuating a control means to cause sputtering of said cladding material onto said plastic tape; removing said cladding material supply from said target position; positioning a supply of fiber core material in said target position; placing an interruption mask over said deposition position, and re-energizing said tape feed and said control means to cause sputtering of said fiber core material through said interruption mask onto a cladded plastic tape.
Claim 3
Dependent Claim
16 words
A process as defined in claim 1 wherein said control means includes a radio frequency generator.
Claim 4
Dependent Claim
27 words
A process as defined in claim 1 wherein said interruption mask is provided with a plurality of slits to definitely position fiber cores on said cladded tape.
