Filed:

May 26, 2000

Appl. No.:

09/580322

Inventors:

Ashish K. Verma - San Jose CA
Arnold C. Chen - Fremont CA
Daniel A. Francis - Oakland CA

Assignee:

Finisar Corporation - Sunnyvale CA

International Classification:

H01S 500

US Classification:

372 45, 372 43, 372 50

Abstract:

A monolithic semiconductor device extends primarily along a vertical direction and includes the following layers. A first semiconductor layer and a second semiconductor layer form an active region between them. A third semiconductor layer is doped the same type as the second semiconductor layer but is lattice mismatched to the second semiconductor layer. The lattice mismatch results in unwanted electrical effects. An additional doping layer, preferably a delta doping layer, is located in close proximity to the interface between the second and third semiconductor layers. The delta doping layer mitigates the unwanted electrical effects introduced by the lattice mismatch. In a preferred embodiment, the device further includes a bottom mirror layer and a top mirror layer, which together form a laser cavity including the active region.

International Classification:

A61B 18/18

US Classification:

606 33

Abstract:

An tissue interface module has an applicator chamber on a proximal side of the tissue interface module and a tissue acquisition chamber on a distal side of the tissue interface module. The applicator chamber may include: an opening adapted to receive the applicator; an attachment mechanism positioned in the applicator chamber and adapted to attach the tissue interface module to the applicator; a sealing member positioned at a proximal side of the applicator chamber; and a vacuum interface positioned at a proximal side of the applicator chamber and adapted to receive a vacuum inlet positioned on a distal end of the applicator. The invention also includes corresponding methods.

US Classification:

606 33

Abstract:

Systems, methods and devices for creating an effect using microwave energy to specified tissue are disclosed herein. A system for the application of microwave energy to a tissue can include, in some embodiments, a signal generator adapted to generate a microwave signal having predetermined characteristics, an applicator connected to the generator and adapted to apply microwave energy to tissue, the applicator comprising one or more microwave antennas and a tissue interface, a vacuum source connected to the tissue interface, a cooling source connected to said tissue interface, and a controller adapted to control the signal generator, the vacuum source, and the coolant source. The tissue may include a first layer and a second layer, the second layer below the first layer, and the controller is configured such that the system delivers energy such that a peak power loss density profile is created in the second layer.
