We experimentally demonstrate efficient third harmonic generation from an indium tin oxide nanofilm (λ/42 thick) on a glass substrate for a pump wavelength of 1.4 μm. A conversion efficiency of 3.3 × 10−6 is achieved by exploiting the field enhancement properties of the epsilon-near-zero mode with an enhancement factor of 200. This nanoscale frequency conversion method is applicable to other plasmonic materials and reststrahlen materials in proximity of the longitudinal optical phonon frequencies.

- Large optical nonlinearity of nanoantennas coupled to an epsilon-near-zero material (2018, background): “It has been reported recently that materials with vanishingly small permittivity – commonly known as epsilon-near-zero or ENZ material – exhibit intriguing linear [12, 13, 14, 15, 16] and large nonlinear responses [17, 18, 19, 20, 21].”
