Abstract
A new scheme for a compact, continuously tunable terahertz source based on photoconductive antenna arrays is presented. Narrowband terahertz radiation is generated by superposition of time-delayed wideband radiations from an array of sub-picosecond photoconductive antennas. We demonstrate an 8 muW average power, radiation bandwidth of 0.05 THz, and a tuning range of 0.65-1.4 THz, through a 2.5times10 mm2 photoconductive antenna array prototype.
