Shining a light on ... light
Dinesh Basker applied to graduate schools around the world. He was accepted to three, but you might say he "saw the light" in choosing McMaster.
Two in one solution for low cost polymer LEDs and solar cells
UNIST researchers report considerable improvement in device performance of polymer-based optoelectronic devices. Published in Nature Photonics today, the new plasmonic material, can be applied to both polymer light-emitting diodes ...
Mirror, mirror on the wall, who has the lowest noise of them all
Although it may not be immediately obvious, the mechanical properties of optical components have a significant impact on the performance of lasers employed in precision sensing applications. Currently, the ...
Large wave-vector phonon modes in silicon nanomembranes
(Phys.org) —Modified large wave-vector phonons in semiconductor membranes via hard X-ray thermal diffuse scattering (TDS) were observed that provide new insight into the fundamental thermal and electronic ...
The first electrically powered nanolasers capable of being operated at room temperature
(Phys.org) —Significant proof of the critical importance of long term basic research funding has been demonstrated with the first convincing operation of a room temperature, continuous wave nanolaser powered by electricity.

(Phys.org) —The use of graphene in telecommunications could dramatically accelerate internet speeds by up to a hundred times, according to new research by scientists in our Department of Physics.
Jagged graphene edges can slice into cell membranes
(Phys.org) —A collaboration of biologists, engineers, and material scientists at Brown University has found that jagged edges of graphene can easily pierce cell membranes, allowing graphene to enter the ...
New phenomenon could lead to novel types of lasers and sensors
There are several ways to "trap" a beam of light—usually with mirrors, other reflective surfaces, or high-tech materials such as photonic crystals. But now researchers at MIT have discovered a new method ...
Universe's secrets closer thanks to ultrafast lasers
Research from the Institute of Photonics and Quantum Sciences (IPaQS) at Heriot-Watt, has the potential to revolutionise how we observe the universe using telescopes, with a new approach that exploits ultrashort ...
Studying waves over astronomical distances
Tiny pulses of light one billionth of a second apart, travelling further than from the Earth to Sun, were used in an exquisitely sensitive experiment at The University of Auckland to explore fundamental interactions between ...
