International Classification:

H04M 11/10

US Classification:

455413, 4554141, 455417, 455421, 4554121

Abstract:

A service is provided to cell phone subscribers to improve reachability. A home location register node maintains state information on a subscriber's cell phone status. Cell phone status information includes: off; on, registered and available to receive calls; on, registered but busy participating in an ongoing call; on, registered but temporarily unavailable; and on, registered but unattended. Temporarily unavailable is further qualified: poor reception location, high interference, cell throughput saturation, intentional user disposition. Long term unavailability may also be inferred and indicated depending on the device and/or system status. When a call to a subscriber's cell phone cannot be completed or is not answered, the service annunciates the reason to the calling party. The calling party can then make a more informed decision as to when to reattempt the call and is more likely to reattempt the call. The service is provided in conjunction with call forwarding to landlines phones and/or voicemail.

US Patent:

50695614, Dec 3, 1991

Filed:

Jul 24, 1990

Appl. No.:

7/557276

Inventors:

William C. Rideout - Townsend MA
Roger P. Holmstrom - Wayland MA
Elliot Eichen - Arlington MA
William Powazinik - Marlborough MA
Joanne LaCourse - Hudson MA
John Schlafer - Wayland MA
Robert B. Lauer - Stow MA

Assignee:

GTE Laboratories Incorporated - Waltham MA

International Classification:

H01S 319

US Classification:

385 14

Abstract:

A monolithically integrated optical preamplifier comprises an amplifying region, an optical detection region for detecting amplified light, and an optically transparent and electrically insulating isolation region interposed between the amplifying and optical detection regions. The amplifying region achieves reduced facet reflectivity by being designed to have a large spot size, single-traverse mode waveguide amplifier oriented at an angle with respect to a crystal plane through the preamplifier. The isolation region is preferably an air gap.

Assignee:

GTE Laboratories Incorporated - Waltham MA

International Classification:

G02B 636

US Classification:

350 9620

Abstract:

A localized cooling method allows the sequential alignment and soldering of one optical fiber at a time to a semiconductor package, while previously aligned and soldered optical fibers are held fixed. This method utilizes the mechanical property of a sharp melting point eutectic alloy solder or a pure metal solder for the fiber connections and is effective for multi-fiber optoelectronic packages demanding stability and high precision. A package design for optoelectronic components requiring multi-fiber alignment incorporates this feature of localized cooling internally. The localized cooling method and the novel package utilizing this method internally make it possible to eliminate the tilted angle optical fiber alignment problem by mounting tilted facet optical amplifier components at a predetermined offset angle.

International Classification:

H01S 319

US Classification:

372 50

Abstract:

A monolithically integrated multiple-wavelength laser structure includes an array of lasing structures each having a cavity length chosen to correspond to a desired lasing wavelength. The array is suitable for use as a transmitter in a wavelength division multiplexing communication system. The lasing structures preferably include quantum well active regions.

International Classification:

H01S 319

US Classification:

372 50

Abstract:

An optical preamplifier includes a semiconductor optical amplifier monolithically integrated with an optical detector and electrically isolated from the detector by an isolation region. The isolation region consists of a low-loss, preferably transparent, insulating material whose index of refraction is matched to at least the refractive index of the amplifier, leading to reduced facet reflectivity at the amplifier output facet. Alternative device structures may include a waveguiding layer in the isolation region, a grating integrated with or following the optical amplifier, and a tuning region positioned between the amplifier and isolation region for filtering spontaneous emission.

International Classification:

G02B 636

US Classification:

350 9620

Abstract:

A method of compensating for the angular coupling of optical fibers to a tilted facet optoelectronic component involves a precise calculation of the coupling angle with respect to the active layer of the component and with respect to the side walls of the package in which the component is to be mounted. With these angles computed, the tilted facet component is positioned on a carrier at an offset to the perpendicular such that input/output fibers can exit the component package perpendicularly to its sidewalls. The component is secured to the carrier by a solder having a high melting point such that subsequent soldering of parts to the carrier will not affect the component positioning. A localized cooling method then allows the sequential alignment and soldering of one optical fiber at a time to the offset tilted facet component, while previously aligned and soldered optical fibers are held fixed. This method utilizes the mechanical property of a sharp melting point eutectic alloy solder or a pure metal solder for the fiber connections and is effective for multi-fiber optoelectronic packages demanding stability and high precision.
