Formation and investigation of infrared sources with the active medium of GaAsBi quantum formations

Operation co-funded by EU cohesion policy (European Social Fund (ESF)) under the programme EU Structural Funds Investments - LT - ERDF/ESF/CF/YEI (2014LT16MAOP001), managing authority: Finansų ministerija. The source names no beneficiary for this operation. Location: Vilnius County (NUTS LT011); Lithuania. Budget: total eligible expenditure EUR 1,877.93; EU co-financing EUR 1,877.93 (co-financing rate 100%), as stated by the source. Runs 2019-07-01 to 2019-08-31. Source: Kohesio, EU cohesion policy projects managed by national and regional authorities (not CORDIS); selected because its title uses a quantum word. Summary from Kohesio (English machine translation by the source): The aim of the proposed project is the development of near-infrared (NIR) sources — lasers with the active medium of GaAsBi quantum formations — and optimisation of design. The project will focus on the technology of multiple GaAsBi quantum pits fluorescent at wavelengths between 1.0 and 1.3 µm using molecular fibre epitaxia. During the project, different GaAsBi laser structures will be grown: optically accumulating surface emitting semiconductor lasers (VECSEL) and electro-accumulated laser emitting diodes (Fabry-Perot type). Laser structures of different design and growing conditions will be characterised by X-ray diffraction, photoluminescence, microscopy of atomic forces, scanning electron microscopy and translucent electron microscopy to determine the relationship between technological parameters and laser characteristics. These radiation sources could be used for environmental protection of atmospheric pollution, “green” home monitoring, air and water pollution measurement. Future applications are also linked to medical spectroscopic systems and biosensors for non-invasive disease recognition and imaging, the food industry to detect very low doses of toxic bio-products.
