LT-GaAs photoconductive antenna excited at 1550 nm for near-field terahertz detection
The 9th International Symposium on Ultrafast Phenomena and Terahertz Waves (2018), paper WI18(2018)
Abstract
Terahertz near-field imaging is an emerging technology for fundamental research and life science. We presented a new near-field detection technique using LT-GaAs photoconductive antenna at 1550 nm. The system achieves a 70 dB dynamic range and 4 THz bandwidth.
