Infrared spectroscopy with visible light

Spectral measurements in the infrared optical range provide unique fingerprints of materials, which are useful for material analysis, environmental sensing and health diagnostics1. Current infrared spectroscopy techniques require the use of optical equipment suited for operation in the infrared range, components of which face challenges of inferior performance and high cost. Here, Kalashnikov et al. develop […]

Plasmonic Device Achieves 90-GHz Switching

Plasmonic Device Achieves 90-GHz Switching

DURHAM, N.C., July 27, 2015 — Able to flip on and off 90 billion times a second, a new plasmonic light emitter could form the basis of optical computing. “This is something that the scientific community has wanted to do for a long time,” said Duke University professor Maiken Mikkelsen, whose team developed the device. […]

Plasmon Wakes Created, Controlled in Metamaterial

Plasmon Wakes Created, Controlled in Metamaterial

CAMBRIDGE, Mass., July 7, 2015 — Surface plasmons can exhibit wakes likes any other wave, and those wakes can be controlled through nanoscale features on a metallic surface and through properties of the light shining on it. The creation and control of surface plasmon wakes could lead to new types of plasmonic couplers and lenses […]

Computational plasmonics: an ab initio and multiscale perspective

November 2, 2015 to November 4, 2015 Location : CECAM-HQ-EPFL, Lausanne, Switzerland Description The goal of the present workshop is to bring together the different communities working in computational plasmonics, to address open questions such as: • How to identify a plasmon excitation in electronic structure method results? How do excitations transform from molecular-like to […]

Experiment confirms quantum theory weirdness

Experiment confirms quantum theory weirdness

27 MAY 2015 The bizarre nature of reality as laid out by quantum theory has survived another test, with scientists performing a famous experiment and proving that reality does not exist until it is measured. Physicists at The Australian National University (ANU) have conducted John Wheeler’s delayed-choice thought experiment, which involves a moving object that […]

A Monolithic White Laser

A Monolithic White Laser

Valerie C. Coffey A white-light laser has the potential to replace white LEDs in lighting, displays, sensing and telecom, with higher energy conversion efficiencies and higher output powers. But multicolor lasing from a small, monolithic semiconductor-based laser has remained elusive due to fundamental challenges in materials and structures. Researchers at the Arizona State University (ASU; […]
