Honeywell International, Inc. - Morristown NJ

International Classification:

G06F 19/00

US Classification:

702 19

Abstract:

An apparatus and method for detecting an agent utilizes a substrate, a waveguide on the substrate, a light source, a photo-detector, an optical coupler on the substrate, and a processor. The light source is configured to emit light into the waveguide. The photo-detector is configured to detect light. The optical coupler is configured to direct a first portion of light propagating from the waveguide towards the photo-detector and to direct a second portion of the light propagating from the waveguide back into the waveguide. The waveguide and the optical coupler at least partially form a resonator. A substance is at least one of embedded within the waveguide and adjacent to the waveguide. The substance is reactive to the agent. The processor detects a change in a resonance lineshape of the resonator caused by the reaction of the substance to the agent.

International Classification:

G01C 19/72

US Classification:

356464

Abstract:

Systems and methods for environmentally insensitive high-performance fiber-optic gyroscopes are provided. In one embodiment, a loop closure electronics apparatus for a fiber optic gyroscope having an optical phase modulator characterized by a transfer function that includes an error component of at least second order is provided. The apparatus comprises: a first digital circuit that generates a digital bias modulation signal; a second digital circuit that generates a digital feedback signal; at least one digital-to-analog converter that produces an electrical signal that drives the phase modulator from the digital bias modulation signal and the digital feedback signal; and a compensator that includes an analog filter of at least second order and a digital filter of at least second order, wherein the analog filter and the digital filter pre-filter the electrical signal to compensate for the error component.

International Classification:

G03F5/00

US Classification:

430394

Abstract:

A method and apparatus for printing vertically and horizontally aligned features having reduced, substantially equal, critical dimensions on a photoresist-coated semiconductor wafer are disclosed. Radiant energy is passed through a pattern transfer tool to irradiate a first region of the wafer when the wafer is at a first position relative to the pattern transfer tool. The wafer is then positioned at a second position relative to the pattern transfer tool offset from the first position by a first distance along an axis aligned with the horizontal features and by a second distance along an axis aligned with the vertical features. The second distance is different from the first distance by a compensation distance. Radiant energy is then passed through the pattern transfer tool to irradiate a second region of the wafer region defining a second side of each of the horizontally and vertically aligned features.

H01S 3/04
H01S 3/094
H01S 3/106

Abstract:

A micro femtosecond laser with reduced radiation and temperature sensitivity is provided. The laser includes a housing with a radiation shield. Optical components that include a micro gain element are received within the housing. An input end of a pump light delivering fiber is positioned outside the housing. An output end of the pump light delivering fiber is positioned within the housing to deliver input beams to the optical components. A light signal generating pump is used to generate the input beams that are communicated to the input end of the pump light delivering fiber. A first end of a hollow core fiber is positioned within the housing to be in optical communication with the optical components. A second end of the hollow core fiber is positioned outside the housing. A partially reflective output coupling mirror is in optical communication with the second end of the hollow core fiber.

Abstract:

An integrated optical circuit comprises a first waveguide section of a first material having a first index of refraction, a second waveguide section diffused with a second material, different from the first material, the second waveguide section having a second index of refraction; and a third waveguide section of the first material. A portion of the first waveguide section at a first interface is angled at a first angle and a portion of the second waveguide section is angled at the first angle. A portion of the first waveguide section at a second interface is angled at a second angle and a portion of the third waveguide section is angled at the second angle. The first angle and second angle are selected such that the angle of incidence of light at the first and second interfaces is greater than the Brewster's angle.
