Abstract

Metasurfaces able to concentrate light at various wavelengths are promising for enhancing nonlinear interactions. In this Letter, we experimentally demonstrate infrared second-harmonic generation (SHG) by a multi-resonant nanostructure. A 100 GaAs layer embedded in a metal-insulator-metal waveguide is shown to support various localized resonances. One resonance enhances the nonlinear polarization due to the transverse magnetic (TM)-polarized pump wavelength near $3.2\;{\unicode{x00B5}{\rm m}}$, while another is set near the TE-polarized generated wavelength ($1.6\;{\unicode{x00B5}{\rm m}}$). The measured SHG efficiency is higher than ${10^{- 9}} \;{{\rm W}^{- 1}}$ for pump wavelengths ranging from 2.9 to $3.3\; {\unicode{x00B5}{\rm m}}$, which agrees with theoretical computations. This is typically 4 orders of magnitude higher than the equivalent GaAs membrane.
