Abstract

We report on phase matched THz emission from GaAs using the anomalous dispersion introduced by optical phonon absorption at the reststrahlenband in GaAs. For this system tunability of the emitted THz frequencies by changing the near infrared excitation wavelength is predicted. We investigate this phenomenon for an oversized double metallized GaAs waveguide. A shift in the THz spectra is observed when the near-infrared wavelength is varied. Enhanced emission is found when phase matching is achieved at 1.4 µm.

Index of refraction of semi-insulating GaAs calculated from time domain spectroscopy data. The red solid line is the calculated refractive index assuming a Lorentz oscillator model. The parameters for the calculation are ω0 = 268.7 cm−1 (8.1 THz) for the resonance, εstat = 12.8, ε = 10.8 are the static and high frequency dielectric constants, respectively. The damping constant in GaAs is γ = 2.4 cm−1 [9,10].

THz emission from GaAs-slab plotted in dependence of excitation wavelength. It illustrates the peak to peak value of the THz field in the time domain (a) the relative bandwidth of the emitted spectra (b). Squares represent the experimental data, while the solid line serves as a visual guide. Excitation was again by the OPA laser system with constant pulse energy of 0.2 µJ.
