Phase 2 STTR

Institution: University of Wisconsin, Madison

Agency: Army
Topic: A15A-T003
Budget: 09/12/16 - 09/11/17
PI: Dan Botez

The technical objectives of this proposal are: 1) Fabricate and test ridge-guide, quantum-cascade-laser (QCL) devices employing a broad-gain-spectrum active-region design and suitable for incorporation in the designed high-index-contrast (HC) photonic-crystal (PC) THz, difference-frequency-generation (DFG) QCLs ; 2) Fabricate and test large-aper...

Topic: N13A-T006
Budget: 03/23/15 - 03/15/16
PI: Dan Botez

The technical objectives of this proposal are: (1) demonstrate a 4.6 micron-emitting grating-coupled surface-emitting (GCSE) quantum cascade laser (QCL) designed for incorporation in an Active-Photonic-Crystal (APC) structure; (2) demonstrate a high-index-contrast APC-QCL edge-emitting structure, designed for incorporation of gratings; (3) demon...

Phase 2 STTR

Institution: University of Wisconsin, Madison

Agency: Navy
Topic: N12A-T003
Budget: 07/09/14 - 04/09/15

The technical objective of this proposal is to demonstrate a Quantum Cascade Laser (QCL) emitting in the 3.0-3.5 µm wavelength region, which employs a metamorphic buffer layer (MBL). It is the goal of this program to develop a QCL single-stripe device which will operate in a single, diffraction-limited lobe under room temperature continuous-wave...
