High-Intensity THz Radiation Pulses from a Scalable Large-Aperture Emitter

Winnerl, S.; Krenz, M.; Dreyhaupt, A.; Stehr, D.; Dekorsy, T.; Helm, M.

Using a novel metal-semiconductor-metal (MSM) structure, we combine a large-active-emitter volume with strong electric fields for carrier acceleration. We obtain THz field amplitudes of 6 kV/cm using excitation pulse energies of 10 µJ.

Keywords: Terahertz emitter; photoconductive materials; ultrafast processes in semiconductors
