A nonlinear metasurface combining telecom-range intersubband transitions in GaN/AlN quantum wells with resonant plasmonic antenna arrays
Jan Mundry, Florian Spreyer, Valentin Jmerik +3
We realize and investigate a nonlinear metasurface taking advantage of intersubband transitions in ultranarrow GaN/AlN multi-quantum well heterostructures. Owing to huge band offse…

Non-Degenerate Two-Photon Absorption in ZnSe: Experiment and Theory
L. Krauss-Kodytek, W. -R. Hannes, T. Meier +2
We experimentally and theoretically investigate the non-degenerate two-photon absorption coefficient in the prototypical semiconductor ZnSe. In particular, we provide…
