Abstract We study supercontinuum generation (SC) in graphene-covered nanowires based on a generic model that correctly accounts for the evolution of the photon number under Kerr and two-photon absorption processes, and the influence of graphene is treated within the framework of saturable photoexcited-carrier refraction. We discuss the role of the various effects on the generation of supercontinuum by a thorough analysis of short-pulse propagation in two different kinds of graphene-covered nanowires, one made of silicon nitride and the other made of silicon. Finally, we discuss the effect of stacking graphene layers as a means to enhance SC generation with pulse powers compatible with those in integrated optical devices.

Good Agreement

We performed sub-ps pulse-propagation experiments around the biexciton two-photon resonance in CuCl, and confirmed the soliton-like propagation of exciton–polariton pulses proposed by one of us [Phys. Rev. Lett.75, 224 (1995)]. In our scheme two-photon nonlinearity compensates exciton–polariton dispersion, and pulse propagate without distortion. We compared our results with the calculated ones and obtained a good agreement between them.
