Abstract

This work presents the generation of pulsed THz radiation from a quantum dot photoconductive antenna (PCA) pumped at 800nm. The work investigates the output and characteristics of the generated THz from the QD PCA alongside a comparison with a commercial antenna from Teravil. The QD PCA outputs significantly higher THz power at low pump powers than the commercial PCA and would therefore be suitable for any application that would require a low-pump power such as the use of semiconductor lasers as pump sources for THz generation.
