Non-Destructive, Sub-Angstrom Level Measurement Of A Nanofiber
1/23/2017
Researchers at the University of Maryland's Joint Quantum Institute (JQI) and the Army Research Laboratory (ARL) have devised a unique method to measure the radius of a nanofiber with sub-angstrom-scale sensitivity — without destroying the nanofiber with chemicals and heat in the process, as current scanning electron microscopy (SEM) techniques tend to do.

Finnish Researchers Use Plasmonic Nanolaser In Dark And Bright Modes
1/5/2017
Researchers at Aalto University in Finland have demonstrated for the first time a new lasing technique operating at visible light frequencies, in both bright and dark modes, by utilizing metallic nanoparticles arranged in a periodic array. Their findings make possible the creation of small and ultrafast on-chip light sources.

Building A Single-Atom Quantum Optical Circulator
12/12/2016
Scientists at the Technische Universität Wien (TU Wien) in Vienna, Austria have devised a new method to control the flow of light along perpendicular and intersecting glass fibers using a single atom. Building such a nanoscale optical element for controlling light, including single photons, can be important for optical signal processing of quantum information.

Scientists Improve Modulation Bandwidth, Laser Operation Of Transistor Laser Device
12/8/2016
Engineers Nick Holonyak Jr. and Milton Feng at the University of Illinois continue to enhance the remarkable properties of the transistor laser they invented in 2004. Two of their recent studies explain how they improved the fundamental modulation bandwidth of the transistor and the laser operation of the device to make possible energy-efficient, high-speed data transfer in optical and 5G wireless communications.
