US Classification:

370546, 370259, 37920101

Abstract:

Systems and methods for providing a communication bridge between a physical location and a virtual location are provided. In particular, the presence of a visitor to a physical location is detected, and notification of the presence of a visitor is provided to a user associated with the physical location. The notification may include an identification of the visitor. Following notification, real-time communications between the visitor at the first physical location and the user at the virtual location are established, without requiring entry of a communication address for the virtual office of the user by the visitor.

International Classification:

G06F 12/00

US Classification:

709245, 709206, 709223

Abstract:

The present invention provides methods, devices, and systems for managing message distribution lists. More specifically, the message distribution list may be location-specific and the recipients listed in the list may be dynamically updated based on their detected presence with respect to a particular location. By dynamically updating a message distribution list based on presence information, recipients of the message can be provided with a greater assurance that the messages they receive are locally relevant.

US Patent:

43027296, Nov 24, 1981

Filed:

May 15, 1979

Appl. No.:

6/039424

Inventors:

Robert D. Burnham - Los Altos Hills CA
Donald R. Scifres - Los Altos CA
William Streifer - Palo Alto CA

Assignee:

Xerox Corporation - Stamford CT

International Classification:

H01S 319

US Classification:

331 945H

Abstract:

A solid state laser in which transverse mode control is achieved by a layer of non-uniform thickness adjacent the laser active region and longitudinal mode control is achieved by a periodic structure formed in the laser substrate. The layer of non-uniform thickness is provided by forming the layer on a channeled substrate, and the teeth of the periodic structure extend in a direction transverse to the direction of the channel.

Appl. No.:

6/075381

Inventors:

Robert D. Burnham - Los Altos Hills CA
Donald R. Scifres - Los Altos CA
William Streifer - Palo Alto CA

Assignee:

Xerox Corporation - Stamford CT

International Classification:

H01S 319

US Classification:

331 945H

Abstract:

Improved lateral carrier and optical confinement is achieved in heterostructure diodes and lasers having a Fabry-Perot cavity transverse to the plane of the p-n junction of the device. Structural features during fabrication improve carrier confinement to the active region in the established optical cavity. Current confinement means is also fabricated above and below the active region to concentrate the current density to the active region in the optical cavity and thereby improve the overall gain of the device. Such confinement also enhances optical confinement along the cavity. Several reflector structures are disclosed for employment at the cavity ends to provide optical feedback.

Appl. No.:

5/518335

Inventors:

Donald R. Scifres - Los Altos CA
Robert D. Burnham - Los Altos Hills CA

Assignee:

Xerox Corporation - Stamford CT

International Classification:

H01L 750

US Classification:

156 7

Abstract:

A structure for providing arrays or individual hemispherical diodes and methods of producing the diodes. When the diode array is to be part of a configuration utilizing a substrate, the substrate is selected to have radiation transparency, a lower refractive index, and lattice constant and lattice structure similar to that of a crystal layer grown in hemispheres formed in the substrate. When the diode array is to be removed from the substrate, a material that can be preferentially etched is grown between the hemispheres formed in the substrate and the grown crystal layer that is to have light emitting areas.

Appl. No.:

6/268596

Inventors:

Robert D. Burnham - Palo Alto CA
Donald R. Scifres - Los Altos CA
William Streifer - Palo Alto CA

Assignee:

Xerox Corporation - Stamford CT

International Classification:

H01S 319

US Classification:

372 45

Abstract:

In a semiconductor injection laser with a nonplanar pattern in the substrate, growth of the plurality of layers comprising the laser structure is accomplished in vapor phase epitaxy to produce a lateral spatial thickness variation (LSTV) in the active region of the laser. The LSTV profile is one of or combination of the profiles disclosed in FIG. 2, producing an effective, although small, lateral refractive index variation in the active region, thereby permitting the maintenance of the lowest order transverse mode along the plane of the active region.

Donald R. Scifres - Los Altos CA

Assignee:

Xerox Corporation - Stamford CT

International Classification:

H01S 319
H01S 3081

US Classification:

331 945C

Abstract:

A heterojunction diode laser which produces a highly collimated, polarized light beam perpendicular to the plane of the PN junction of the laser rather than through cleaved end faces in the plane of the PN junction. The diode laser includes a periodic structure which is buried at a heterojunction interface and in contact with a light waveguide layer. The periodic structure acts to produce the feedback necessary for lasing. If the spacing of the teeth of the periodic structure are an integer number of wavelengths of the light photons produced in the laser, the light beam exits at an angle perpendicular to the plane of the PN junction. If a tooth spacing is chosen that is not equal to an integer number of wavelengths of the light photons produced in the laser, the light beam may emerge from the diode at an angle other than the normal with the specific angle determined by the particular tooth spacing. To increase output intensity, the ends of the laser perpendicular to the plane of the PN junction and parallel to the teeth of the periodic structure may be cleaved and coated with a highly light reflective film.
