New nanolasers for quantum information sources
May 1st, 2016

Integrating coherent light sources at the nanoscale with spasers is one of the most promising applications of plasmonics. In a spaser, localized plasmon polaritons (LPPs) waves occurring at the metal-dielectric interface are amplified by an active medium. Under specific conditions, the gain of plasmonic modes can overcome the absorption losses occurring in the metal and […]

Harnessing Disorder at the Nanoscale: Anderson localization in nanoplasmonic systems
November 23rd, 2015

It is a common perception that the presence of disorder influences negatively the properties of a physical system. Nevertheless, there are several cases in which disorder plays a positive role and can be exploited to develop novel applications. In general, the introduction of disorder significantly increases the complexity of the system under examination, but, as […]

Super dark chameleon nanomaterials (Guinness World Record as the ‘darkest material created by man’)
October 22nd, 2015

Black, technically, is not a color but the absence of colors. It is the complete opposite of white or the presence of all colors. Something appears black because it does not reflect light or absorbs most of the light that hits its surface. Conversely, something appears white because it reflects all of the colors that […]

Tailoring disorder in plasmonic nanolenses for cancer screening
September 4th, 2015

The collaboration of the teams of professors Enzo Di Fabrizio and Andrea Fratalocchi at the King Abdullah University of Science and Technology (KAUST), in Saudi Arabia, has led to the development of a new device that enables the detection of mutations down to a single amino acid. The conceptual technique – plasmonic self-similar chain – […]
