Objective: To investigate the characteristics of quantum dots as components of lasers and reflective coatings through the analysis of the impact of various methods of their fabrication and processing. These factors significantly influence the performance, reliability, and spectral characteristics of optoelectronic devices.

Results: The study of the influence of quantum dot parameters, such as size and shape, on their optical properties, including bandgap width and luminescent characteristics, as well as the assessment of how these parameters affect the structural and functional characteristics of nanostructures, allows for a deeper understanding of the potential applications of quantum dots in modern optoelectronic devices. This data contributes to the development of more efficient laser technologies and reflective coatings.

Practical Significance: The presented work is crucial for deepening knowledge about quantum dot lasers and other radiation sources in the optical range. Investigating their characteristics and potential applications opens new horizons for developing highly efficient laser technologies and optoelectronic devices. The results obtained may serve as a foundation for creating high-precision sensors and actuators in nanoelectromechanical systems, which is particularly relevant for onboard systems of small spacecraft. This will significantly enhance the reliability and performance of optical systems used in space research and other high-tech fields.
