Quantum cascade laser roadmap
Carlo Silvestri, Aleksandar D. RakiÄ, 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…

Detectorless 3D terahertz imaging: achieving subwavelength resolution with reflectance confocal interferometric microscopy
Jorge Silva, Martin Plöschner, Karl Bertling +18
Terahertz imaging holds great potential for non-destructive material inspection, but practical implementation has been limited by resolution constraints. In this study, we present…
