Filed:

Dec 14, 2001

Appl. No.:

10/022757

Inventors:

Scott W. Corzine - Sunnyvale CA, US
Michael Renne Ty Tan - Menlo Park CA, US
Chao Kun Lin - Fremont CA, US
Jintian Zhu - Palo Alto CA, US
Michael H. Leary - Fremont CA, US

Assignee:

Agilent Technologies, Inc. - Palo Alto CA

International Classification:

G02B001/10

US Classification:

359584, 359359, 359585

Abstract:

A distributed Bragg reflector and a method of fabricating the same incorporates a support for supporting the gaps against collapse. The method includes forming a plurality of alternating structure and sacrificial layers on a substrate. The structure and sacrificial layers are etched into at least one mesa protruding from the substrate. A support layer is formed on the at least one mesa leaving a portion of the structure and sacrificial layers exposed. At least a portion of at least one of the exposed sacrificial layers are etched from between the structure layers to form gaps between the structure layers.

International Classification:

H01S 3/08
H01S 5/343

US Classification:

372 96, 372 4401

Abstract:

A vertical-cavity surface-emitting laser incorporating a supported air gap distributed Bragg reflector is disclosed. The supported air gap DBR includes a regrowth layer of material that provides mechanical support for the original material layers. The supported air gap DBR is fabricated by first growing alternating pairs of a first material and a sacrificial material over a suitable substrate. The layer pairs of the first material and sacrificial material are covered by a suitable dielectric material. The dielectric material is then selectively removed exposing regions of the first material and sacrificial material where selective regrowth of additional material is desired. The selective regrowth of the additional material provides mechanical support for the semiconductor material that remains after a selective etch removal of the sacrificial material.

G06K 9/00

Abstract:

A method for generating a road map for vehicle navigation comprises: receiving an original road map having a crossroad junction, an inward lane entering the crossroad junction, and an outward lane leaving the crossroad junction; generating a reference path capable of guiding a vehicle driving from the inward lane to the outward lane through the crossroad junction; generating a polygonal hub that encompasses the crossroad junction, wherein the reference path enters and leaves the hub by crossing a first binder and a second binder, respectively; and generating automatically a type of the reference path based on the geometrical relationship between the first binder and the second binder.

Abstract:

A method for generating a road map for vehicle navigation comprises: providing original road image data having an image of a road; identifying boundary lines defining respective lane segments of the road from the original road image data; associating traffic properties with the lane segments defined by the boundary lines, respectively; grouping the lane segments to generate road segments; and combining the road segments with traffic control objects corresponding thereto so as to generate the road map for vehicle navigation.
