Title
Study and development of advanced nanostructured spin-lasers
Code
SP2019/9
Summary
Spin-lasers are semiconductor devices in which recombinations of spin-polarized electrons in active region (quantum wells and dots) lead to emission of circularly-polarized photons [1-3]. The possibility of using and modulation of spin-polarized electrons together with including low-dimensional nanostructures (periodical gratings, quantum wells, quantum dots) opens new horizons in modern semiconductor research and information technology. Proposed project will be focused on theoretical and experimental study of effects in such advanced structures together with their optimalization and developments.
