Eyesafe Lidar for Stand-Off Bioaerosol Detection and Plume Tracking

Not Available The development of a high performance laser with low relative intensity noise (RIN) for RF photonics application is proposed. The laser has a modulation doped multi-quantum well active region and is fabricated on a p-type substrate. The former is needed for low RIN because the modulation doped multi-quantum well design increases the resonance frequency, and the latter is needed for low inter-modulation distortion because p-substrate based buried heterostructure lasers reduce leakage currents and hence improve linearity. Measurements and analysis of integrated electroabsorption modulated lasers for RF photonics application will also be carried out. A modulated doped multi-quantum well laser will be fabricated and characterized in Phase I with design optimization planned for Phase II. The best design identified at the end of Phase I will be optimized, fabricated, measured and packed for prototype delivery in Phase II.
