Low-threshold RNGH instabilities in quantum cascade lasers
NN Vuković, J Radovanović… - IEEE Journal of …, 2017 - ieeexplore.ieee.org
We show that low-threshold Risken-Nummedal-Graham-Haken (RNGH) instabilities in
quantum cascade lasers (QCLs) occur due to a combined effect of the carrier coherence and …
