About

Giacomo Scalari is a leading figure in the field of terahertz (THz) photonics, with a particular focus on quantum cascade lasers (QCLs) and their applications in spectroscopy and sensing. His major contributions center on the development of innovative THz QCL designs, including pioneering work on photonic crystal and metal-metal waveguide structures that dramatically improve device performance and beam quality. Scalari’s research has been instrumental in pushing THz QCLs toward higher operating temperatures and broader frequency tunability, enabling their use in advanced spectroscopic systems for chemical detection and imaging. His work has garnered significant impact, with his most-cited paper accumulating over 70 citations, reflecting its influence on the miniaturization of smart instruments for biomedical applications. Notably, Scalari has been recognized for his role in advancing THz technology, including contributions to the European project TERACAN, which aims to develop THz systems for cancer diagnostics. His research continues to bridge the gap between fundamental photonics and practical, high-impact devices for sensing and medical diagnostics, making him a key figure in the THz community.
