Second-order nonlinear optical susceptibility for gapped graphene

POSTER

Abstract

The second-order nonlinear optical susceptibility $\chi^{(2)}$ for second harmonic generation is calculated for gapped graphene. The linear response plasmon excitation as well as the second-order nonlinear plasmon excitations are investigated. We report a red shift which is an order of magnitude enhancement of that resonance with growing gap, or alternatively, reduced electro-chemical potential.
