US Patent:

6580741, Jun 17, 2003

Filed:

Jun 18, 2002

Appl. No.:

10/175338

Inventors:

Wenbin Jiang - Calabasas CA
Hsing-Chung Lee - Calabasas CA
Yong Cheng - Thousand Oaks CA

Assignee:

E2O Communications, Inc. - Calabasas CA

International Classification:

H01S 500

US Classification:

372 50, 372 75

Abstract:

An integrated optically pumped vertical cavity surface emitting laser (VCSEL) is formed by integrating an electrically pumped in-plane semiconductor laser and a vertical cavity surface emitting laser together with a beam steering element formed with the in-plane semiconductor laser. The in-plane semiconductor laser can be a number of different types of in-plane lasers including an edge emitting laser, an in-plane surface emitting laser, or a folded cavity surface emitting laser. The in-plane semiconductor laser optically pumps the VCSEL to cause it to lase. The in-plane semiconductor laser is designed to emit photons of relatively short wavelengths while the VCSEL is designed to emit photons of relatively long wavelengths. The in-plane semiconductor laser and the VCSEL can be coupled together in a number of ways including atomic bonding, wafer bonding, metal bonding, epoxy glue or other well know semiconductor bonding techniques. The beam steering element can be an optical grating or a mirrored surface.
