Abstract(s) :

(Anglais) Driven linear and non-linear photonic cavities are extensively studied. Indeed, it can exhibit non-reciprocity, frequency conversion, thermal cooling,.... It is known that injected noise in a bistable modulated system can lead to periodic transitions between stable states, a phenomenon called stochastic resonance. Recently, it has been shown both experimentally and numerically that such phenomenon can, for example, enhance energy harvesting. Here, for the first time, we present stochastic resonance resulting from temperature-induced noise as well as a modulated monochromatic pump. We study thermal radiation and outgoing power from a non-linear photonic cavity coupled to an external channel. The cavity is driven by a modulated monochromatic pump and its mode evolution is described as a stochastic process due to temperature-induced noise. Such system exhibits frequency conversion and paves the way for temporal control of radiative heat transfer. We also suggest a semi-analytical approach for the estimation of coherent outgoing power into the external channel in the stochastic resonance regime.
