Cascaded third-harmonic generation in hybrid graphene-semiconductor waveguides

Smirnova, Daria; Solntsev, Alexander


We study cascaded harmonic generation of hybrid surface plasmons in integrated planar waveguides composed of a graphene layer and a doped-semiconductor slab. We derive a comprehensive model of cascaded third-harmonic generation through phase-matched nonlinear interaction of fundamental, second-harmonic, and third-harmonic plasmonic modes supported by the structure. We show that hybrid graphene-semiconductor waveguides can simultaneously phase-match these three interacting harmonics, increasing...[Show more]
