Appl. No.:

09/639552

Inventors:

Carol M. Ford - Columbia Heights MN

Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

C23C 1414

US Classification:

427531, 427 58, 427123, 4271263, 427131, 427132, 427162, 427523, 427547, 427598

Abstract:

A method for fabricating a magneto-optic modulator, such as for use with a solid state ring resonator gyroscope. The method includes inducing a magnetic field at a substrate holder as a layer of magnetic material is being deposited on a substrate. The magnetic field helps to optimally orient the deposited magnetic material layer to improve the characteristics of the magneto-optic modulator. In addition to inducing a magnetic field, a low energy ion beam may be applied to optimize orientation. The method can be used to fabricate a magneto-optic modulator on a substrate containing a partially fabricated ring resonator without destroying previously fabricated components.

US Classification:

216 2, 216 33, 438455, 228193

Abstract:

A method of bonding and packaging components of Micro-Electro-Mechanical Systems (MEMS) and MEMS based devices using a Solid-Liquid InterDiffusion (SLID) process is provided. A micro-machine is bonded to a micro-machine chip using bonding materials. A layer of chromium is first deposited onto surfaces of the micro-machine and the micro-machine chip followed by a layer of gold. Subsequently, a layer of indium is deposited between the layers of gold, and the surface of the micro-machine is pressed against the surface of the micro-machine chip forming a gold-indium alloy to serve as a bond between the micro-machine and the micro-machine chip. In addition, a cover is bonded to the micro-machine chip in the same manner providing a hermetic seal for the MEMS based device.

International Classification:

G02B 626

US Classification:

385 30

Abstract:

An optical waveguide is created using the process of ion beam deposition resulting in a waveguide with low propagation loss, mode discrimination, and gain characteristics. The waveguide is made up of a multilayer stack which is deposited upon a thermally stable substrate, wherein the multilayer stack comprises alternating layers of a first material and a second material. The layers of second material are doped with a rare earth material. By pumping the waveguide with a pump light source, interaction between the pump light and the rare earth material within the waveguide causes amplification or gain of a first optical signal. Ion beam deposition is used to fabricate the waveguide, therefore production of a high quality rare earth doped waveguide is possible. Furthermore, the waveguide is made using batch processing thus reducing costs.

International Classification:

H01S 3097

US Classification:

372 87

Abstract:

A cathode for a laser generator includes a monolithic substrate consisting essentially of a nonconductive material and including a thin film of a conductive material deposited thereon. The substrate has an inner and outer surface, the thin film substantially contiguously covers the substrate and prevents exposure of the substrate over the life of the cathode, and the conductive thin film is oversprayed onto a portion of the substrate's outer surface so as to allow electrical contact from the outer surface to the inner surface.

International Classification:

G01C 1966

US Classification:

356350

Abstract:

An apparatus and method for prevention of migration of mobile ions in a gyroscope. A dielectric barrier material layer is placed between a gyroscope body and one or more gyroscope components. The dielectric barrier material layer reduces the electric field formed in the gyroscope block, and thus reduces ion migration therein. The material may prevent mobile ions from reaching the cathode seal.

Abstract:

A sintered dense laser block constructed of ceramic metal composition manufactured through sintering, conventional machining and electro discharge machining. A ceramic metal powder and binder are combined and shaped into a laser block. The laser block is then sintered to permit electro-discharge machining. After detailed machining various subsequent firings will yield different dielectric properties for the laser block. Other laser gyro ceramic parts may be manufactured with the method of the invention such as mirror assemblies, cathodes and laser path length controllers. The electro-discharge machining permits the construction of complex ceramic shapes from a slurry of powdered ceramic metal and binder which has been extruded or shaped and then conventional machined. The resulting part is cheaper and easier to make and the electro-discharge machining provides a method of creating very complex shapes in the part.
