Mid-Infrared Interband Cascade and Quantum Cascade Lasers for Chemcial Sensing

Phase 1 SBIR

Agency: Department of Energy
Topic: 2003
Budget: 01/01/03 - 12/31/03
PI: Dr. John D. Bruno

70109S02-II Monitoring the development and proliferation of nuclear materials and weapons is an important national objective. Several gases are emitted during the processing of nuclear materials, and their presence at trace levels essentially establishes that nuclear materials are being processed at a given location. However, presently avai...

Epi-Side-Down-Mounted Interband Cascade Laser with Improved Top Cladding Layer

Phase 1 SBIR

Agency: Army
Topic: A02-123
Budget: 12/10/02 - 06/23/03
PI: Dr. John D. Bruno

In this Phase I program, we will assess semiconductor diode laser technology to determine which semiconductor lasers are the best candidates for meeting infrared countermeasure (IRCM) requirements in each of the three IRCM wavelength bands. A central focus of the effort will be to test the feasibility and merits of a new design for type-II inter...

Thermal Modeling, Design, and Testing of Epi-Side-Up-Mounted Interband Cascade Lasers

Phase 1 SBIR

Agency: Defense Advanced Research Projects Agency
Topic: SB022-044
Budget: 10/10/02 - 06/10/03
PI: Dr. John D. Bruno

In this Phase I program, we will assess the feasibility and merits of a new method/design for fabricating epi-side-up-mounted type-II interband cascade (IC) lasers. These mid-IR IC lasers, based on cascaded type-II InAs/Ga(In)Sb/AlSb quantum wells, have recently demonstrated pulsed operation at 300K, but cw operation has been severely limited by...

Development of Intra-Cavity-Injection Mid-IR Interband Cascade Laser

Phase 1 SBIR

Agency: Department of Energy
Topic: 2002
Budget: 01/01/02 - 12/31/02
PI: Dr. John D. Bruno

70109 Monitoring the development and proliferation of nuclear materials and weapons is an important national objective. Several gases are emitted during the processing of nuclear materials, and their presence at trace levels at a given location essentially establishes that nuclear materials are being processed there. However, presentl...

Distributed Feedback Interband Cascade Lasers

Phase 1 SBIR

Agency: Missile Defense Agency
Topic: BMDO01-003
Budget: 05/09/01 - 11/09/01
PI: Dr. Rui Q. Yang

In this program, we propose to develop single-mode distributed feedback (DFB) interband cascade lasers based on type-II InAs/Ga(In)Sb/AlSb quantum wells. These semiconductor diode lasers will emit in the 3-5 micron mid-IR wavelength region and operate in quasi-CW mode. The DFB interband cascade lasers retain the advantages of cascade inject...

Mid-Infrared Vertical Cavity Surface Emitting Cascade Lasers

Phase 1 SBIR

Agency: Missile Defense Agency
Topic: BMDO01-014
Budget: 05/08/01 - 11/07/01
PI: Dr. Rui Q. Yang

In this program, we propose to develop vertical cavity surface emitting lasers (VCSELs) based on cascaded type-II InAs/Ga(In)Sb/AlSb quantum wells, which will operate in the 3-7 microns mid-IR wavelength region in quasi-CW mode with output power exceeding 1 mW. The type-II interband cascade VCSELs retain the advantages of cascade injection ...

Mid-IR Photodetectors Based on Type-II Quantum Wells

Phase 1 SBIR

Agency: Missile Defense Agency
Topic: BMDO00-003
Budget: 12/28/00 - 06/28/01
PI: Dr. Rui Q. Yang

In this program, we propose to develop complex superlattices based on type-II InAs/Ga(In)Sb/AlSb heterostructures for mid-IR (~3-12 microns) detectors. These type-II InAs/Ga(In)Sb/AlSb heterostructures have relatively larger electron effective masses compared to the state-of-the-art IR material HgCdTe, leading to a strong reduction of leakage c...
