Abstract
Using a hydrodynamic approach, we examine bulk- and surface-induced second- and third-harmonic generationfrom semiconductor nanowire gratings having a resonant nonlinearity in the absorption region. We demonstrateresonant, broadband, and highly efficient optical frequency conversion: contrary to conventional wisdom, weshow that harmonic generation can take full advantage of resonant nonlinearities in a spectral range where non-linear optical coefficients are boosted well beyond what is achievabl...
