Abstract
We demonstrate efficient generation of quasi-single-cycle THz pulses using an interdigitated GaAs Large Area Photoconductive Antenna LAPCA with a binary phase mask. The binary phase mask results in a time-delayed excitation of the GaAs antenna, which allows subsequent antennas to produce an additive field. The resulting of this additive field is the generation of a quasi single cycle Thz pulse. We demonstrate control over the temporal profile of the THz waveform to maximize optical-to-THz conversion efficiency, and investigate temporal shaping of the THz field using different phase masks.
