Observation of the Turn-on Delay in InAs- and InP-based Quantum Cascade Lasers under Pulsed Pumping with Non-zero Rise-time

2021 
We observe unexpectedly long turn-on delay reaching 10ns and its non-monotonous dependence on pumping amplitude in InAs- and InP-based quantum-cascade lasers under non-zero rise-time pulse-pumping. Our numerical simulations qualitatively agree with these measurements.
