Abstract:
A highly sensitive terahertz (THz) detector based on a photoconductive antenna (PCA) with plasmonic amplification on the basis of an InGaAs/InAlAs superlattice heterostructure is proposed. A noticeable increase in the photocurrent recorded by a plasmonic PCA detector and the signal-to-noise ratio was experimentally detected compared to the same parameters for the PCA detector without plasmonic electrodes. The efficiency of plasmonic electrodes has been experimentally confirmed by pulsed THz spectroscopy by measuring the dependence of the detector’s THz signal amplitude on the polarization of the incident pump laser radiation.
This study was carried out with the financial support of the Ministry of Education and Science of the Russian Federation (state order no. FSFZ-0706-2020-0022; experimental studies of temporal and spectral characteristics of THz radiation) and the Russian Foundation for Basic Research (project no. 20-32-70129; manufacturing and general characterization of samples).
