Filed:

Dec 29, 1998

Appl. No.:

09/223088

Inventors:

Jesse A. Vaught - Phoenix AZ
Karl A. Fetting - Glendale AZ
Henry H. Hung - Paradise Valley AZ
John H. Shannon - Scottsdale AZ

Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

G02B 612

US Classification:

385 14

Abstract:

An Integrated Optics Chip (IOC) package for an IOC, including a base having an upper support surface having a first raised surface and a dielectric gel disposed on the first raised surface of the base and adapted to couple to the IOC. The dielectric gel is sufficiently compliant to minimize stresses from structural changes in the base, accommodate a thermal mismatch between the IOC and the base, and reduce vibration. A first adhesive may be applied to a platform integral to the base that is sufficiently rigid to prevent the IOC from separating from the dielectric gel during vibration. A second adhesive may be applied on a second raised surface of the base to provide strain relief to the leads of the IOC. Advantages include the elimination of several components and manufacturing steps, improved strain relief and vibration dampening, as well as manufacturing time and cost savings.

International Classification:

US Classification:

385 11, 385 31, 385 50, 385 96, 385 97, 385 99

Abstract:

In many optics applications, it is desirable to retard the polarization of a light wave, i. e. , to change the polarization state of a light wave. In a method for retarding polarization of a light wave, a first linear polarization-maintaining fiber having a first beat length is spliced to a second polarization-maintaining fiber having a high birefringence and a second beat length. The second fiber is then cleaved to a length which is a fraction of the second beat length. The first fiber and the second fiber may be secured in a removable or permanent capillary. A light wave is transmitted into the first fiber and the polarization state of the light wave is determined. To adjust the polarization state, the second fiber may be lapped against an abrasive substance. The second fiber may be repeatedly lapped until a desired polarization state is achieved. In an alternate method, a first linear polarization-maintaining fiber is spliced to a second polarization-maintaining fiber having a high birefringence and a beat length.

Assignee:

Polymicro Technologies, LLC - Phoenix AZ

International Classification:

G02B 636

US Classification:

385 78

Abstract:

The invention includes a ferrule having a layer of material on an inner surface of a hole therein which is selected to be preferentially softenable relative to the bulk material of the ferrule. The ferrule according to the present invention can be fused to optical fibers, capillaries and the like while reducing deformation of the fused component and the ferrule. A fiber Bragg grating device and a flow cell device are also provided.

US Classification:

385 95, 385 11, 385136

Abstract:

The polarization state of a light wave is changed by a fiber polanrzation retardation device constructed by a method including employment of a pair of clamping fixtures, and a series of steps including clamping, cleaving, splicing, releasing, clamping, and cleaving, so as to achieve precise optical fiber lengths to achieve a desired polarization retarding device.

International Classification:

G02B 6245

US Classification:

385 51

Abstract:

A housing for fiber optic components reduces stress on optical fibers and protects the components from environmental shock and vibration. The housing includes a protective body having a receiving space wherein the fiber optic component is positioned. A rigid adhesive applied to the fibers in a specific stress reducing profile near the ends of the receiving space secures the component out of contact with the wall of the receiving space without inducing stress on the jacketless optical fibers. A gel support material fills the receiving space surrounding the component and providing vibration isolation. The invention is particularly uses for housing fiber optic couplers which are subject to shock, vibration, and temperature extremes.

Assignee:

Maxwell Laboratories, Inc. - San Diego CA

International Classification:

H01J 724

US Classification:

378119

Abstract:

A transmission line connecting a power supply, for supplying power pulses, to a load disposed inside of a vacuum chamber. Electrically conductive debris in both gaseous and non-gaseous forms is generated in response to the application of the power pulse to the load. The transmission line includes first and second conductors electrically connecting the power supply to the load. An insulator extends between the conductors and partially defines the vacuum chamber. A dump for debris in non-gaseous form is disposed between load and the insulator and the transmission line further includes a system for ejecting gaseous debris from between the conductors so that substantial debris is prevented from accumulating on the insulator, which accumulation, if allowed to form, could result in flashover of the transmission line.

International Classification:

G01C 1972

US Classification:

356350

Abstract:

A fiber optic gyroscope that includes an improved winding transition section otherwise known as a "jog zone". The improved jog zone reduces losses due to micro-bends and cross-coupling in the fiber optic coil. The reduced losses enable a more accurate measurement of rotation rate of the fiber optic coil, while minimizing unwanted phase-shifts that can cause false readings in the fiber optic gyroscope.
