Effect of current on terahertz plasmons in AlGaN/GaN heterostructures
M. Dub, P. Sai, Y. Ivonyak +3
Terahertz transmittance spectra of plasmonic crystals based on two-dimensional electron gas in AlGaN/GaN heterostructures were studied in grating-gate and gateless plasmonic crysta…

Extreme Terahertz Nonlinearity of AlGaN/GaN-based Grating-Gate Plasmonic Crystals
Pavlo Sai, Vadym V. Korotyeyev, Dmytro B. But +12
We present a novel approach to enhance THz nonlinearity by the resonant excitation of two-dimensional plasmons in grating-gate plasmonic crystals. Using a high-electric-field THz p…
