We investigate the nonlinear optical properties of single resonant plasmonic antennas fabricated from heavily-doped Germanium films. Excitation with intense and ultrashort midinfrared pulses at 10.8 μm wavelength produces emission at 3.7 μm via third-harmonic generation.

Abstract
We investigate the nonlinear optical properties of single resonant plasmonic antennas fabricated from heavily-doped Germanium films. Excitation with intense and ultrashort midinfrared pulses at 10.8 μm wavelength produces emission at 3.7 μm via third-harmonic generation.File in questo prodotto:
