Title
Modeling and experimental study of dynamical effects in semiconductor spin-lasers with reduced symmetry and 1D periodical gratings
Code
SP2018/51
Summary
Spin-polarized lasers with a vertical configuration (spin-VCSELs) are currently and widely studied for the perspective application in information technology and cryptography. In such devices recombination of spin-polarized carriers leads to the emission of circularly-polarized photons, which change their polarization state during a propagation in anisotropic layers [1,2]. The proposed project is dedicated to i) theoretical and experimantal study of such anisotropies: surface and interfacial anisotropies in semiconductor quantum wells due to the D2d – C2v symmetry reduction, ii) semiclassical, quantum, and experimental study od dynamical properties of spin-population inversion and a impact of the local anisotropies on them, and iii) study of the electromagnetic waves and photons propagation in the laser structures with 1D periodical gratings.
