Operation of Fabry-Perot laser with nonlinear PT-symmetric mirror [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2021 The above-threshold operation of a Fabry-Perot laser with a nonlinear PT (parity time) mirror is investigated. For the first time, the analysis accounts for gain saturation of an active medium as well as gain and loss saturation effects in the PT mirror.
