TOPTICA?s TeraScan helps characterize next-generation terahertz detectors
A team of researchers from Frankfurt University, Ferdinand-Braun Institute (both Germany) and Vilnius University (Lithuania) has managed to significantly improve the performance of TeraFETs, using GaN-based high-electron mobility transistors (HEMTs).
(PresseBox) - So-called ?TeraFETs? - field-effect transistors with integrated antennas for terahertz detection - are promising candidates for compact, chip-based, yet broadband terahertz receivers.
A team of researchers from Frankfurt University, Ferdinand-Braun Institute (both Germany) and Vilnius University (Lithuania) has managed to significantly improve the performance of TeraFETs, using GaN-based high-electron mobility transistors (HEMTs). The sensitivity of the new devices was more than twofold higher than with previous GaN terahertz detectors.
The authors employed a TeraScan 1550 from TOPTICA Photonics as a precisely tunable terahertz source in order to characterize the new detectors over a broad frequency range.
