Filed:

Oct 10, 2002

Appl. No.:

10/268461

Inventors:

Kenneth R. Schroll - Chatham NJ, US
James P. Waters - Boonton Township NJ, US
Richard T. Kane - Morristown NJ, US
Peter M. Fried - Madison NJ, US
Janet Mrotek - Somerset NJ, US

Assignee:

General Dynamics Advanced Information Systems, Inc. - Arlington VA

International Classification:

G02B006/26

US Classification:

385 30, 385 27, 385 42, 385 50

Abstract:

A first optical fiber is coupled to a second optical fiber by ablating a portion of the cladding from the first and second optical fibers, thus exposing or nearly exposing the fibers' cores, bringing the ablated regions close together in the presence of an optical couplant, adjusting the alignment of the fibers so as to achieve a desired optical coupling ratio, and securing the fibers relative to each other. The ablation can be accomplished using a laser. The fibers can be secured mechanically or using adhesives. The finished coupler can be sleeved or otherwise encapsulated for physical protection. The technique can be applied to pairs of fiber ribbons, each having multiple optical fibers.

Filed:

Jun 17, 1997

Appl. No.:

8/877075

Inventors:

Richard Thomas Kane - Morristown NJ

Assignee:

Lucent Technologies Inc. - Murray Hill NJ

International Classification:

G02B 602
G02B 622

US Classification:

385127

Abstract:

The present applicant has discovered that an optical filter can be made by etching away part of the cladding of a depressed-cladding fiber. The etching produces a section of fiber having a double peak in the index profile. In a low index medium such as air, the remaining cladding portion guides radiation at certain wavelengths. This radiation is extracted from the radiation in the fiber core.
