  • Abstract
    A photoconductive terahertz (THz) emitter with an integrated Bragg mirror is presented. The emitter exhibits improved emission efficiency by a factor of 10 with respect to an emitter without a mirror. In addition, we demonstrate for the first time the electrical modulation of the THz output radiation with frequencies up to 100 kHz.
