Quantum cascade laser roadmap
Carlo Silvestri, Aleksandar D. Rakić, Dragan Indjin +46
Quantum cascade lasers (QCLs) are unipolar semiconductor lasers first demonstrated in 1994. Since then, they have played a central role in advancing mid-infrared and terahertz phot…
Probes for Ultrasensitive THz Nanoscopy
Curdin Maissen, Shu Chen, Elizaveta Nikulina +2
Scattering-type scanning near-field microscopy (s-SNOM) at terahertz (THz) frequencies could become a highly valuable tool for studying a variety of phenomena of both fundamental a…
Understanding the image contrast of material boundaries in IR nanoscopy reaching 5 nm spatial resolution
Stefan Mastel, Alexander A. Govyadinov, Curdin Maissen +3
Scattering-type scanning near-field optical microscopy (s-SNOM) allows for nanoscale resolved Infrared (IR) and Terahertz (THz) imaging, and thus has manifold applications ranging…
Probing low-energy hyperbolic polaritons in van der Waals crystals with an electron microscope
Alexander A. Govyadinov, Andrea Konečná, Andrey Chuvilin +8
Van der Waals (vdW) materials exhibit intriguing structural, electronic and photonic properties. Electron Energy Loss Spectroscopy (EELS) within Scanning Transmission Electron Micr…
Theoretical and numerical investigation of the size-dependent optical effects in metal nanoparticles
Alexander A. Govyadinov, George Y. Panasyuk, John C. Schotland +1
We further develop the theory of quantum finite-size effects in metallic nanoparticles, which was originally formulated by Hache, Ricard and Flytzanis [J. Opt. Soc. Am. B 3, 1647 (…
Phaseless three-dimensional optical nano-imaging
Alexander A. Govyadinov, George Y. Panasyuk, John C. Schotland
We propose a method for optical nano-imaging in which the structure of a three-dimensional inhomogeneous medium may be recovered from far-field power measurements. Neither phase co…
