Abstract

By using a tunable TEA CO₂ laser and by grating coupling at the interface of GaAs–Al, we have obtained, for the first time to our knowledge, second-harmonic generation from a resonantly excited infrared surface polariton. The experimental results provided a dispersion relation that compares well with theoretical calculations. The deduced value of χ⁽²⁾, 5.9 × 10⁻⁷ esu, agrees well with other measurements.
