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.
Claims3
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.
