Appl. No.:

10/602298

Inventors:

Bernd Witzigmann - Burbank CA, US
Trinh D. Nguyen - San Gabriel CA, US

Assignee:

Emcore Corporation - Albuquerque NM

International Classification:

H01S 5/00

US Classification:

372 4301

Abstract:

A high-speed, directly modulated ridge waveguide laser includes: a ridge structure at a junction surface of the laser chip; and a plurality of pads only on non-active areas of the junction surface, where the plurality of pads protrude beyond an edge of the ridge structure. The laser chip can thus be held by a manufacturing tool, such that the manufacturing tool abuts the pads without abutting the ridge structure. In this manner, the ridge structure of the laser is protected from damage due to contacts by manufacturing tools, increasing the device yield of a wafer. By providing the pads only on the non-active areas of the junction surface, parasitic capacitance for contacts in the active areas can be properly controlled.

Abstract:

Apparatus and methods for managing, manipulating and presenting data objects within a graphical user interface with variable dimensions, shapes, locations and interactions. The apparatus and methods allow for variable data objects to be both pinned and liquid depending on a larger management and manipulation apparatus. The apparatus consists of databases that store the data objects to be displayed within the user interface and the layout coordinates, variable potential object size, and whether the object can move or not based on the graphical user interface dimensions. The object manipulations include the representation of such objects on the graphical user interface in a defined sequence.
