Stochastically sustained population oscillations in high-β nanolasers

New Journal of Physics, 2013
Nonlinear dynamical systems involving small populations of individuals may sustain oscillations in the population densities arising from discrete changes in population numbers due to random events.

Polariton lasing in Mie-resonant perovskite nanocavity

Opto-Electronic Advances
Deeply subwavelength lasers (or nanolasers) are highly demanded for compact on-chip bioimaging and sensing at the nanoscale. One of the main obstacles for the development of single-particle nanolasers with all three dimensions shorter than the emitting ...

How small can “Nano” be in a “Nanolaser”?

Nanophotonics, 2012
We show that the lasing threshold of the single mode metal-semiconductor nano-laser (spaser) is determined only by the photon absorption rate in the metal and exhibits very weak dependence on the composition, shape, size (as long as it is less than half ...
