Novel Infrared Point Sources

There is a need for broadband infrared light source for simulation projection systems operating at room temperature. We are proposing to develop tunable quantum cascade infrared light emitters based on III-V nitride semiconductors. During Phase I, the proposed emitter will be designed and fabricated. Electro-luminescence in the infrared will be measured at room temperature and low temperatures. In Phase II, the design and growth conditions will be optimized and prototype IR light emitters with multi-wavelength emission bands will be built and evaluated. Successful completion of the project may provide low-cost efficient infrared light sources covering 2 to 14 microns.
