New nanolasers for quantum information sources
May 1st, 2016PRIMALIGHT News, Research highlightsJuan Sebastian Totero Gongora 0 Comments

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, 2015PRIMALIGHT News, Research highlightsJuan Sebastian Totero Gongora 0 Comments

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’)

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, 2015PRIMALIGHT News, Research highlightsJuan Sebastian Totero Gongora 0 Comments

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 – […]

Complex metallic nanocrystals for plasmon-enhanced catalysis
August 13th, 2015Research highlightsJuan Sebastian Totero Gongora 0 Comments

Colloidal metal nanocrystals with strong, stable, and tunable localized surface plasmon resonances (SPRs) can be useful in a corrosive environment for many applications including field-enhanced spectroscopies, plasmon-mediated catalysis, etc. Here, a new synthetic strategy is reported that enables the epitaxial growth of a homogeneously alloyed AuAg shell on Au nanorod seeds, circumventing the phase segregation […]

Complex optical forces: towards the optical sorting of biological matter
May 21st, 2015Research highlightsJuan Sebastian Totero Gongora 0 Comments

In recent years, the interest in the study of the interaction between light and biological matter has largely increased. While optics has historically been mainly used for imaging applications, light has now become a tool of manipulation and direct interaction with biological samples. It is well known that when light impinges on an object it […]

Tsunami on-chip: the power to harness catastrophic events

Harvesting energy from chaos
December 5th, 2014Research highlights, UncategorizedMarcella Bonifazi 0 Comments

Chaos is a phenomenon that occurs in many aspects of contemporary science. In classical dynamics, chaos is defined as a hypersensitivity to initial conditions. The presence of chaos is often unwanted, as it introduces unpredictability, which makes it difficult to predict or explain experimental results. Conversely, we demonstrate here how chaos can be used to […]

Experimental demonstration of Superradiant optical materials
December 4th, 2014Research highlightsChangxu Liu 0 Comments

Superradiance—a cooperative phenomenon originally predicted by Dicke in 1954 for two-level atoms—consists of ubiquitous collective dynamics. Such an effect has been observed in a huge number of systems, both quantum and classical. Despite a large body of theoretical results, however, many questions about superradiance are still debated; this lack of experimental evidence originates, in part, […]
