Abstract:

An integrated circuit/optoelectronic packaging system () which comprises OE and IC components packaged to provide electrical input/output, thermal management, an optical window, and precise passive or mechanical alignment to external optical receivers or transmitters. A transparent insulating substrate having electrical circuitry in a thin silicon layer formed on its top side is positioned between the optical fiber and the optoelectronic device such that an optical path is described between the optoelectronic device and the optical fiber core through the transparent insulating substrate. The optoelectronic devices are mounted on the transparent insulating substrate in a precise positional relationship to guide holes in the substrate. The optical fibers are fixed in an optical fiber connector and are held in a precise positional relationship to guide holes in the connector. Alignment is accomplished with complementary guide pins that pass through guide holes in the fiber optic connector and in the transparent substrate.

Abstract:

A method and apparatus for optically clocked optoelectronic track and hold (“OCOETH”) device. The OCOETH device includes a diode bridge, input node, at least two current sources and at least two photodetectors. The input node is operatively coupled to the diode bridge and can receive an analog input signal. The at least two current sources are operatively coupled to the diode bridge and can forward bias the diode bridge. The at least two photodetectors are operatively coupled to the diode bridge and can receive an optical input clocking signal, and can reverse bias and forward bias the diode bridge in response to the optical input clocking signal. The hold capacitor is operatively coupled to the diode bridge and can track the analog input signal when the diode bridge is forward biased, and can hold the analog input signal when the diode bridge switches from forward biased to reverse biased.

International Classification:

G01B 902

US Classification:

356350

Abstract:

An improvement for a fiber interferometer gyro provides for greater rotation rate sensitivity. The gyro has a single mode fiber coiled about an identical area a great number of times. A single external laser sends pulses of energy which are split and passed in opposite directions through the coiled fiber and a pair of optical amplifiers inserted to amplify the energy pulses. This permits the length of the coiled fiber to be increased and, hence, provides for greater interferometer sensitivity.

International Classification:

G02B 630

US Classification:

350 9617

Abstract:

A micromanipulator and UV curing adhesive allows a precise end-on coupling of an optical fiber to a film optical waveguide on a substrate. Such a coupling facilitates the optical processing of data on active or passive optoelectronic chips with the inherent advantages of parallel, high speed capability. After coarse STATEMENT OF GOVERNMENT INTEREST The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalties thereon or therefor. BACKGROUND OF THE INVENTION Technological advances in optical communications and in optical data processing have seen the emergence of thin-film optical and electro-optical logic elements in conjunction with optical fibers and have led to high speed signal processing concepts wherein fibers would be used as interconnecting optical channels, delay lines or shift registers. Thin film guided wave devices are strong candidates to perform terminal functions in optical fiber communication systems. These applications require practical fiber-to-thin film coupling methods and in some cases precise specification and control over the optical delay from one integrated optical element through an optical fiber to another integrated optical element via some coupling regions.

International Classification:

H04B 900

US Classification:

380 54

Abstract:

An apparatus for a method for assuring the secure transmission of information between a transmitter and a receiver is fabricated along the lines of a Mach-Zehnder interferometer. Two, identical length single-mode fibers extend between the transmitter and receiver to act as transmission paths. Within the transmitter a coiled length of like single-mode fiber integrally extends from one of the fibers reaching from the transmitter to the receiver. Within the receiver a like length of like single-mode fiber integrally extends from the other end of the other fiber reaching from the transmitter to the receiver. A superradiant diode in the transmitter emits pulses of coherent wavetrains that are split and sent through the two lengths of fibers and their associated integrally connected coils. A detector in the receiver senses variations in the interference fringes when a modulator in the transmitter shifts in path length the coherent wavetrains in one of the fibers in accordance with the information desired to be transmitted. Because of the integrally extending coils in the transmitter and the receiver, an intruder to the system would be unable to find where the transmission paths are identical and hence would be unable to monitor the modulated interference fringe patterns.

US Classification:

359614

Abstract:

A light stop having at least one appropriately laser textured surface assures the absorption of energy including laser emissions that impinge on the at least one surface to thereby inhibit reflected energy therefrom. Optionally, an improved emitter of energy is created by at least one appropriately laser textured surface having an increased surface area of emission to increase the emissive power of the surface to thereby provide improved conductive and radiative cooling. An improved absorber and emitter is fabricated by providing front side and backside textured surfaces. All these capabilities are provided in a variety of structural configurations.
