THz from photoconductive antennas using circular and cylindrical Microlens arrays
We study the THz radiation emission from interdigitated Photo-Conductive Antennas (iPCAs) fabricated on Semi-insulating GaAs substrates and excited using 800nm, 10fs, 76MHz laser pulses through circular and cylindrical Microlens arrays put over the antennas. THz emission is an order of magnitude higher from cylindrical micro-lens array compared to circular micro-lens array, at the same bias voltage. The line excitation appears to be more efficient in generating THz than a point excitation.
