Multiple Wavelength Quantum Dot Lasers (MW-QDL)

Metadata Updated: November 12, 2020

An innovative method to achieve optical gain over a wide spectral range using new laser materials is being investigated.  Multiple wavelength quantum dot lasers (MW-QDL) will be designed to generate emission and gain over a range of wavelengths from the UV-vis to MIR spectral regions.  New quantum dot laser materials will be characterized and the best candidate materials will be chosen for MW-QDL. A new method for generating tunable wavelengths employing quantum dot lasers is being investigated. Quantum dots will be engineered to produce emission and laser gain over a range of wavelengths from the UV-vis to mid-infrared spectral regions.  Atmospheric species such as O3, CO2, NO2, and CH4 will be targeted for predication of the consequences of atmospheric sciences. These molecules have numerous strong optical resonances in the mid-infrared.   However, according to the Decadal Survey, mid-infrared lasers needed for future missions do not exist.  This project addresses a need for a compact, tunable laser source.
