Wavelength Tunable Laser

US Patent:
6891865, May 10, 2005
Filed:
Feb 15, 2002
Appl. No.:
10/077522
Inventors:
Yong Ma - Simi Valley CA,
Assignee:
Afonics Fibreoptics, Ltd.
International Classification:
H01S003/10
US Classification:
372 20, 372 3, 372 94
Abstract:
A wavelength tunable laser comprising a laser diode and a closed external cavity formed by one or more optical resonators either horizontally or vertically coupled to adjacent waveguides. The optical resonator primarily functions as a wavelength selector and may be in the form of disk, ring or other closed cavity geometries. The emission from one end of the laser diode is coupled into the first waveguide using optical lens or butt-joint method and transferred to the second waveguide through evanescent coupling between the waveguides and optical resonator. A mirror system or high reflection coating at the end of the second waveguide reflects the light backwards into the system resulting in a closed optical cavity. Lasing can be achieved when the optical gain overcomes the optical loss in this closed cavity for a certain resonance wavelength which is tunable by changing the resonance condition of the optical resonator through reversed biased voltage or current injection. Multiple optical resonators may be used to reduce the lasing threshold and provide higher power output.

Self Aligned Diode Fabrication Method And Self Aligned Laser Diode

US Patent:
8045595, Oct 25, 2011
Filed:
Nov 15, 2006
Appl. No.:
11/600618
Inventors:
Yong Ma - Goleta CA,
Assignee:
Cree, Inc. - Durham NC
International Classification:
H01S 5/00
US Classification:
372 45011, 372 4501, 372 4301
Abstract:
A method for fabricating a laser diode comprising providing a laser diode epitaxial structure and depositing a metal layer stack on the epitaxial structure, the stack comprising a contact and sacrificial layer. A ridge is formed in the laser diode epitaxial structure, the stack being the mask forming the ridge. An insulating layer is deposited over the ridge and at least a portion of the sacrificial layer is removed. At least a portion of the insulating thin film at the top of the stack is also removed. A pad metal is deposited in electrical contact with the contact and is insulated from the ridge and laser diode epitaxial structures by the insulating layer.

Wavelength Tunable Laser

US Patent:
2005002, Feb 3, 2005
Filed:
Aug 27, 2004
Appl. No.:
10/928010
Inventors:
Yong Ma - Simi Valley CA,
International Classification:
H01S003/10
US Classification:
372020000
Abstract:
A wavelength tunable laser comprising a laser diode and a closed external cavity formed by one or more optical resonators either horizontally or vertically coupled to adjacent waveguides. The optical resonator primarily functions as a wavelength selector and may be in the form of disk, ring or other closed cavity geometries. The emission from one end of the laser diode is coupled into the first waveguide using optical lens or butt-joint method and transferred to the second waveguide through evanescent coupling between the waveguides and optical resonator. A mirror system or high reflection coating at the end of the second waveguide reflects the light backwards into the system resulting in a closed optical cavity. Lasing can be achieved when the optical gain overcomes the optical loss in this closed cavity for a certain resonance wavelength which is tunable by changing the resonance condition of the optical resonator through reversed biased voltage or current injection. Multiple optical resonators may be used to reduce the lasing threshold and provide higher power output. With monolithic integration, more optical devices can be integrated with the tunable laser into the same substrate to produce optical devices that are capable of more complex functions, such as tunable transmitters or waveguide buses.
