Dynamic Scenarios in Two-State Quantum Dot Lasers, 2015 Excited State Lasing, Ground State Quenching, and Dual-Mode Operation BestMasters Series

André Röhm investigates the dynamic properties of two-state lasing quantum dot lasers, with a focus on ground state quenching. With a novel semi-analytical approach, different quenching mechanisms are discussed in an unified framework and verified with numerical simulations. The known results and experimental findings are reproduced and parameter dependencies are systematically studied. Additionally, the turn-on dynamics and modulation response curves of two-state lasing devices are presented.
