Anomalous Mode Transitions in High Power Distributed Bragg Reflector Quantum Cascade Lasers
Abstract In this paper, an anomalous spectral data of distributed Bragg reflector (DBR) quantum cascade lasers (QCLs) emitting around 7.6 μm is presented. The two-section DBR lasers, consisting of a gain section and an unpumped Bragg reflector, display an output power above 0.6 W in continuous wave...
