Abstract

Illuminated by ultrashort optical pulses, large area multiplex terahertz semiconductor emitters that work on photo-Dember currents and Schottky potentials radiate a directional electromagnetic terahertz pulse which is controlled by the angular spectrum of the incident optical beam. Using the lens that focuses the incident near infra-red pulse, we have demonstrated THz emission focusing in free space and characterized a Gouy phase shift.
