Electro-Optic Generation and Detection of Femtosecond Electromagnetic Pulses
Abstract
Key accomplishments during this period are: (1) The successful demonstration of a new technique for generating subpicosecond electromagnetic pulses using large aperture photoconductors to produce directional and diffraction-limited beams of terahertz radiation; (2) The development of a new electrically-controlled phased array of photoconducting antennas for producing steerable terahertz radiation; (3) The extraction of femtosecond electromagnetic pulses from an electro-optic crystal following their generation by electro-optic Cherenkov radiation, and their subsequent propagation and detection in free space; (4) The measurement of subpicosecond electrical response of a new organic electrooptic material (polymer); (5) The observation of terahertz transition radiation from the surfaces of electro-optic crystals.
