Ultra-small Mode Volume Polariton Condensation via Precision Ion Implantation
Y. C. Balas, X. Zhou, E. Cherotchenko +7
We present a novel method for generating potential landscapes in GaAs microcavities through focused implantation. The ion beam imprints micron-scale patterns of non-radiat…
An effect of a pump pulse rising edge on the QCL build-up time: the analytical approach
Ivan I. Vrubel, Evgeniia D. Cherotchenko, Ksenia V. Kusakina +3
In this work, we provide a simplified theoretical analytical estimation of the quantum cascade laser build-up time, accurately taking into account the main effects: the QCL overhea…
Non-adiabatic polariton condensation in annular optical traps
I. Chestnov, E. Cherotchenko, A. Nalitov
We explore formation and dynamics of nonequilibrium bosonic exciton-polariton condensates in annular optically induced traps. For the vicinity of condensation pumping threshold, we…
