Speed limits apply not only to traffic. There are limitations on the control of light as well, in optical switches for internet traffic, for example. Â鶹ÒùÔºicists at Chalmers University of Technology now understand why it is ...
Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new technique to squeeze infrared light into ultra-confined spaces, generating an intense, nanoscale antenna that ...
Nanoscale patterns designed to bend, deflect and split light can now be fabricated directly on light-emitting diode (LED) surfaces using an innovative etching method developed by A*STAR researchers. The new fabrication scheme ...
Infrared spectroscopy is the benchmark method for detecting and analyzing organic compounds. But it requires complicated procedures and large, expensive instruments, making device miniaturization challenging and hindering ...
Similar to the eye of a hurricane, physicists of research institute AMOLF, the University of Amsterdam and the University of Texas at Austin, have captured light in the eye of an optical vortex. The research will be published ...
A new technique developed by MIT physicists could someday provide a way to custom-design multilayered nanoparticles with desired properties, potentially for use in displays, cloaking systems, or biomedical devices. It may ...
An international research team has studied a new cell visualisation and drug delivery system based on nanoparticles coated with luminescent dye molecules. The particle material and the distance between the dye and the particle's ...
Breakthrough lab-on-a-chip technology that reveals how human cells communicate could lead to new treatments for cancer and autoimmune disorders.
Researchers at Columbia Engineering have demonstrated, for the first time, a chip-based dual-comb spectrometer in the mid-infrared range, that requires no moving parts and can acquire spectra in less than 2 microseconds. ...
As electronic devices and circuits shrink into the nanoscale, the ability to transfer data on a chip, at low power with little energy loss, is becoming a critical challenge. Over the past decade, squeezing light into tiny ...
