The main task of the work is: - search for new, effective optical fibers as structured nanocomposites, molecular and anisotropic media for the latest information technologies, in particular for active Raman media of medium and high-power lasers, conduct a study of the influence of a number of impurity nanocomplexes on the Raman gain profile of single-mode fibers based on quartz glass; - reduce the surface roughness to the subnanometer level; - create a model of a semiconductor sensor based on the use of stochastic characteristics of generation-recombination processes on a single trap. The working hypotheses and ideas of the project are based on the already established possibility of practically accurate approximation of the Raman gain profiles of fibers and their extraction from the spectra in a very wide range of Stokes frequency shifts. The efficiency of oxidation of nanoscale inhomogeneities of a rough surface in photochemical polishing methods can be increased by using the effect of total internal reflection to locally increase the level of electric field strength exclusively in the areas of surface protrusions. The working idea for the biophysics direction in this project is to optimize the sensitivity of sensors by clarifying the mechanisms of formation of sensitive parameters by modeling the relevant processes. Increasing the reliability of sensors by using the “Extended gate” design. Product Description popup.authors Haidamak Anton M. Klimov Oleksandr S. Nikytenko Artem L. Oliinyk Victor V.
