Innovative Optical Amplifier Design by Combining Nanoplasmonics and Optical Microresonators

By combining plasmonics and optical microresonators, researchers at the University of Illinois at Urbana-Champaign have created a new optical amplifier (or laser) design, paving the way for power-on-a-chip applications. [More]
NIST Technique Enables Optical Microscopes to Measure 3D Shapes at Nanometer-Scale Resolution

NIST Technique Enables Optical Microscopes to Measure 3D Shapes at Nanometer-Scale Resolution

Recent experiments have confirmed* that a technique developed several years ago at the National Institute of Standards and Technology (NIST) can enable optical microscopes to measure the three-dimensional (3-D) shape of objects at nanometer-scale resolution—far below the normal resolution limit for optical microscopy (about 250 nanometers for green light).

Resonant Nano Particle Scattering Enable Transparent Displays

Light is a slippery fellow. Stand in a darkened hallway and close a door to a lighted room: Light will sneak through any cracks — it doesn't want to be confined. "Typically, in free space, light will go everywhere," graduate student Chia Wei (Wade) Hsu says. "If you want to confine light, you usually need some special mechanism." [More]
Bead Probe and Optical Microscopy Manipulate 1-nm Synthetic Molecular Machine

Bead Probe and Optical Microscopy Manipulate 1-nm Synthetic Molecular Machine

A research group led by Professor Hiroyuki Noji, Department of Applied Chemistry, Graduate School of Engineering, University of Tokyo, successfully observed and touched the rotational motion of a 1-nm synthetic molecular machine through the application of a single-molecule capturing and manipulation technique using optical microscopy and a bead probe (single-molecule motion capturing), which allows visualization of molecular mechanical motion.

W. M. Keck Foundation Awards $1M Grant for Development of Ultra-Compact X-ray Free Electron Laser

Robert Candler, assistant professor of electrical engineering at the UCLA Henry Samueli School of Engineering and Applied Science, has received a $1 million research grant from the W. M. Keck Foundation to develop an ultra-compact X-ray free electron laser. [More]
Coherent Radiations Could be Developed Within the Water Window

Coherent Radiations Could be Developed Within the Water Window

Ever heard of the water window? It consists of radiations in the 3.3 to 4.4 nanometre range, which are not absorbed by the water in biological tissues. New theoretical findings show that it is possible to develop coherent radiations within the water window. [More]

Nano-Optical Cables May Replace Copper Wiring on Computer Chips

The invention of fibre optics revolutionized the way we share information, allowing us to transmit data at volumes and speeds we’d only previously dreamed of. Now, electrical engineering researchers at the University of Alberta are breaking another barrier, designing nano-optical cables small enough to replace the copper wiring on computer chips. [More]
