The International “Infrared and Terahertz quantum workshop” (ITQW) 2023 

The theme of The Infrared and Terahertz Quantum Workshop (ITQW) is the exploration of novel physical phenomena in quantum- and electromagnetically-engineered photonic materials in the infrared and terahertz frequency ranges and the exploitation of these phenomena to create novel photonic devices and applications. This spectral region is particularly interesting in this respect, owing to relaxed fabrication tolerances, low loss of metals, controllable plasmonic and nonlinear optical properties of semiconductors and 2D materials, the presence of phonon resonances in the dielectric constant, and the ability to engineer intersubband transitions in semiconductor heterostructures.
