Exceptional broadband absorption of nanoporous gold explained by plasmonic resonances at dangling ligaments
Muhammad Salman Wahidi, Maurice Pfeiffer, Xinyan Wu +3
Nanoporous gold (npAu) has emerged as a potential candidate for many optical applications exploiting its large surface to volume ratio and high broadband absorption. However, the p…

Energy dependent Chemical Interface Damping induced by 1-Decanethiol Self-Assembled Monolayer on Au(111)
Maurice Pfeiffer, Gregor B. Vonbun-Feldbauer, Jacob B. Khurgin +5
The chemical interface damping (CID) effect increases the collision frequency of free electrons in metals by changes of the metal surface. We have now experimentally disentangled t…

Pulse Compression by an Optical Push Broom On a Chip
Boyi Zhang, Maurice Pfeiffer, Mahmoud A. Gaafar +5
In this study, we report a first experimental demonstration of pulse compression by a gradual refractive index front moving in a periodically modulated silicon waveguide, the so-ca…
