Abstract
This article gives a review on a novel superlattice detector for terahertz (THz) radiation. The detector was tested with the free-electron laser in the Netherlands. The detector is ultrafast (200 fs) and robust with respect to high laser power. The responsivity of the detector is superior compared to the detectors of comparable temporal resolution and robustness. Further, we developed a ...
Abstract
This article gives a review on a novel superlattice detector for terahertz (THz) radiation. The detector was tested with the free-electron laser in the Netherlands. The detector is ultrafast (200 fs) and robust with respect to high laser power. The responsivity of the detector is superior compared to the detectors of comparable temporal resolution and robustness. Further, we developed a superlattice autocorrelator. Both the superlattice direct detector and the autocorrelator can be operated in a broad frequency band from microwave frequencies up to frequencies above 10 THz. The basis for the detection is the miniband transport in the superlattice (C) 2000 Elsevier Science Ltd. All rights reserved.
