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…
Size dependent photoemission study by electrochemical coarsening of nanoporous gold
Fatemeh Ebrahimi, Xinyan Wu, Maurice Pfeiffer +4
The generation and utilization of hot charge carriers in plasmonic materials have emerged as a topic of significant importance, with profound implications across multiple disciplin…
Reciprocity approach for calculating the Purcell effect for emission into an open optical system
K. M. Schulz, D. Jalas, A. Y. Petrov +1
Based on the reciprocity theorem, we present a formalism to calculate the power emitted by a dipole source into a particular propagating mode leaving an open optical system. The op…
Emission enhancement in dielectric nanocomposites
Dirk Jalas, K. Marvin Schulz, Alexander Petrov +1
We consider emitting nanoparticles in dielectric nanocomposites with varying refractive index contrast and geometry. For that we develop a simple and universal method to calculate…
Comment on "Nonreciprocal Light Propagation in a Silicon Photonic Circuit" in Science 333, 729-733 (2011)
Alexander Petrov, Dirk Jalas, Manfred Eich +4
In the recent article by Feng et al. [Science 333, 729-733 (2011)] a system is proposed with a periodic spatial modulation of refractive index and absorption. It is claimed that th…
