Appl. No.:

09/573976

Inventors:

David W. Stowe - Milford MA
Margaret Manty - Whitinsville MA
Stavros Dariotis - Attleboro MA
Colm V. Cryan - Arlington MA

Assignee:

Thomas Betts International, Inc. - Sparks NV

International Classification:

G02B 632

US Classification:

385 43, 385 37, 385126

Abstract:

The present invention is a fused/taper fiber optic coupler and related methodologies for a fuse/taper fiber optic coupler with an FBG that does not excite cladding modes and maintains the coupling regions of the fibers in the proper relationship to one another without a complex and expensive process. Aspects of the fused/taper fiber optic coupler include the use of optical fibers with a three layer structure. The optical fibers include a photosensitive core layer, a photosensitive inner cladding layer, and a photo-insensitive outer cladding layer. Coupling regions are formed in each optical fiber by removing the outer cladding layer and the coupling regions in each optical fiber are then helically intertwined. The intertwined coupling regions are then heated and drawn forming a tapered area in which an FBG may be written.

International Classification:

G02B 626

US Classification:

385 15, 385 39

Abstract:

An optical fiber Mach Zehnder Interferometer includes a first and second elongate optical fiber having a core and a cladding, first and second couplers wherein the cladding of the first optical fiber is coupled to the cladding of the second optical fiber. The first optical fiber includes a first elongate interfering arm where the first optical fiber extends between the first and second couplers. The first interfering arm includes a miniature bend formed therein. The second optical fiber includes a second elongate interfering arm extending between the first and second couplers and may also include a miniature bend formed therein. The miniature bends are contemplated to be either packed or unpackaged. The fibers may exhibit different coefficients of thermal expansion to maintain the path length differences of the interfering arms.

International Classification:

US Classification:

385100, 385101, 29825, 295921, 174 74 R

Abstract:

The present application is directed towards systems and methods for efficient installation of optical and electrical cable in watercraft. A manufacturer may terminate one end of a cable in a location removed from the watercraft, allowing use of automated cable termination machines for efficiency and consistency of terminations. The single-terminated cable may then be brought to the watercraft and installed by pulling or routing the unterminated end through ductwork and pipes, watertight bulkhead throughways, and cable trays and ladders as necessary, prior to termination. Accordingly, more difficult and expensive on-site labor is reduced, and reliability is greatly increased. Furthermore, many cable tests that require termination but cannot be executed post-installation can be performed prior to installation, to ensure that at least the first termination, performed off-site, is error-free, reducing later troubleshooting and further increasing installation efficiency.

International Classification:

G02B 6134

US Classification:

385 37, 385 96, 385 97

Abstract:

A passive temperature compensating package for a fiber Bragg grating device in which the fiber Bragg grating is written to the fiber prior to the temperature compensation being set. As the temperature of the package increases the fiber is de-stressed and at the desired proper resonant frequency, the fiber containing the fiber Bragg grating is secured to the package. As the package cools and expands, the fiber is pre-stressed and maintains the desired resonant frequency.
