Giant Enhancement of Second-Harmonic Generation in Hybrid Metasurface Coupled MoS(2) with Fano-Resonance Effect

Plasmonic nanostructures have been regarded as potential candidates for boosting the nonlinear up-conversion rate at the nanoscale level due to their strong near-field enhancement and inherent high design freedom. Here, we design a hybrid metasurface to realize the moderate interaction of Fano reson...

description Plasmonic nanostructures have been regarded as potential candidates for boosting the nonlinear up-conversion rate at the nanoscale level due to their strong near-field enhancement and inherent high design freedom. Here, we design a hybrid metasurface to realize the moderate interaction of Fano resonance and create the dual-resonant mode-matching condition to facilitate the nonlinear process of second harmonic generation (SHG). The hybrid metasurface presents dipolar and octupolar plasmonic modes near the fundamental and doubled-frequency wavelengths, respectively, further utilized to enhance the SHG of low-dimensional MoS(2) semiconductors. The maximum intensity of SHG in hybrid metasurface coupled MoS(2) is more than ten thousand times larger than that of other structure-units coupled MoS(2). The conversion efficiency is reported to be as high as 3.27 × 10(−7). This work paves the way to optimize nonlinear light–matter interactions in low-dimensional structures coupled with semiconductors.
