Study in Nature: Engineers Find Better Way to Detect Nanoparticles

It’s long been thought that two’s company and three’s a crowd. But electrical and systems engineers at Washington University in St. Louis and their collaborators have shown that the addition of a third nanoscatterer, complementing two “tuning” nanoscatterers, to a photonics resonator makes for a fascinating physics party. Specifically, the two tuning nanoscatterers set the

Integrated Plasmonic Sources and Detectors Needed for Practical Bio- and Chemical Sensing Plasmonic Circuitry

Integrated plasmonic sources and detectors are imperative in the practical development of plasmonic circuitry for bio- and chemical sensing, nanoscale optical information processing, as well as transducers for high-density optical data storage. Here we show that vertical-cavity surface-emitting lasers (VCSELs) can be employed as an on-chip, electrically pumped source or detector of plasmonic signals, when
