Compact IR Spectrometer Fits on a Chip
ZURICH, Oct. 24, 2019 — In an advance for smartphone spectroscopy, researchers at ETH Zurich have developed a chip about 2 cm2 in size that can be used with a smartphone to analyze infrared (IR) light in the same way a conventional spectrometer would. The researchers demonstrated an integrated single-waveguide Fourier transform spectrometer with an operational bandwidth of 500?nm in the near- and short-IR wavelengths. The prototype device, with a footprint of less than 10?mm2, exploits the electro-optic properties of...
Anapole Lasers Generate Ultrafast Pulses for Managing Nanoscale Optics
THUWAL, Saudi Arabia, Aug. 17, 2017 — Anapole lasers made from semiconductors shaped into energy-storing nanodisks could be used in the development of optically powered neurocomputers. According to researchers, the lasers could be made small enough to fit onto computer circuit boards...
Nanoscale Sensor Provides Clear Optical Fingerprint to ID Pollutants
GÖTEBORG, Sweden, May 2, 2017 — A sensor made with ultrathin nanomaterials could improve environmental sensing by providing an unambiguous optical fingerprint for the detection of molecules.
Optoelectronic Device Speeds Parallel Processing
DAEJEON, South Korea, March 30, 2017 — To increase the speed of data transfer when many microprocessors are used in parallel, a novel device has been developed that uses surface plasmons to mediate optoelectronic imaging. The on-chip plasmonic switching device consists of a 2D disordered...
Nano whispering gallery reduces semiconductor emission lifetime
PHILADELPHIA – Applying the concept of whispering galleries to nanoscale devices drastically reduces emission lifetimes, a key property of light-emitting semiconductors, and shows great potential for the development of new ultrafast photonic devices. ...
IBM, ETH Zurich Open Nanotech Center IBM
Aug 1, 2011 — Based in Armonk, N.Y., and ETH Zurich, a science and engineering university in Switzerland, have opened the Binnig and Rohrer Nanotechnology Center on the campus of IBM Research – Zurich. The facility is the centerpiece of a 10-year...
IBM, ETH Zurich Open Nanotech Center
ZURICH, Switzerland, June 6, 2011 — IBM and ETH Zurich, a science and engineering university, recently hosted more than 600 guests from industry, academia and government during the opening of the Binnig and Rohrer Nanotechnology Center on the campus of IBM Research in Zurich. ...
Nano light mill motor controlled by wavelength changes
BERKELEY, Calif. – A newly developed light mill could lead to a whole new crop of nanoscale devices, including nanoscale solar light harvesters, nanoelectromechanical systems, and nanobots that could manipulate DNA and other biological molecules in vivo. ...
Nanotubes Create Atomic ‘Black Hole’
CAMBRIDGE, Mass., April 7, 2010 — Carbon nanotubes, long touted for applications in materials and electronics, may also be the stuff of atomic-scale black holes. Physicists at Harvard University have found that a high-voltage nanotube can cause cold atoms to spiral inward under...
THz Waves Measure Nanofilms
GAITHERSBURG, Md., May 13, 2009 – A technique that could be an important quality-control tool to help monitor semiconductor manufacturing processes and evaluate new insulating materials has been discovered by researchers at the National Institute of Standards and Techology (NIST)....
Self-Assembled Nanoprisms Form Smectic Crystal
Jan 1, 2006 — Building nanometer-scale devices such as photonic crystals requires assembly techniques of unprecedented accuracy. Developing these techniques can be as difficult as designing the devices and, thus, self-assembly methods — in which the components of...
