Dynamical interplay between ground and excited states in quantum dot laser

Abstract

Semiconductor quantum dot lasers are attractive for multiple technological applications in biophotonics. Simultaneous two-state lasing of ground state (GS) and excited state (ES) electrons and holes in QD lasers is possible under a certain parameter range. It has already been investigated in steady-state operations and in dynamical regimes and is currently a subject of the intensive research.
