Quantum cascade lasers with discrete and non equidistant extended tuning tailored by simulated annealing Open
In this work, we report a new superstructure grating design method for broad, non-equidistant discrete tuning in quantum cascade lasers using the Vernier effect. Our approach is applied to a wafer with gain centred at ∼7.8 μm. Measurements…

Mid infrared quantum cascade laser operating in pure amplitude modulation for background-free trace gas spectroscopy Open
We present a single mode multi-section quantum cascade laser source composed of three different sections: master oscillator, gain and phase section. Non-uniform pumping of the QCL's gain reveals that the various laser sections are strongly…
