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…

Optical vortices by an adaptive spiral phase plate
T. Jankowski, N . Bennis, P. Morawiak +6
An Adaptive Spiral Phase Plate (ASPP) based on liquid crystal (LC) and the transmission electrode technique is theoretically and experimentally demonstrated. This ASPP design enabl…
