Collaboration between Rochester’s Laboratory for Laser Energetics and Sandia National Laboratories receives funding aimed at fusion energy

June 30, 2015

The Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) has announced a two-year, $3.8 million award for Sandia National Laboratories and the University of Rochester’s Laboratory for Laser Energetics (LLE) to study the potential of combining two different technologies to further advance their research efforts to produce controlled fusion reactions. Nuclear fusion joins small atoms […]

Defects in atomically thin semiconductor emit single photons

May 4, 2015

Until now, optically active quantum dots have not been observed in materials consisting of a single layer of atom, also known as 2D materials. Rochester researchers have shown how the 2D material tungsten diselenide can be fashioned into an atomically thin semiconductor that serves as a platform for solid-state quantum dots.

University of Rochester team brings sense of touch to virtual reality

April 30, 2015

Virtual reality has made huge technological gains in the last decade, but the ability to feel your surroundings is not yet a part of many mainstream virtual reality systems. A group of University of Rochester students is trying to change that by creating a jacket and gloves that allow the wearer to feel the surface […]

Generating broadband terahertz radiation from a microplasma in air

April 24, 2015

Researchers in the Institute of Optics have shown that a microplasma created by focusing intense laser pulses in air emits not only visible light, but also electromagnetic pulses at terahertz frequencies that can be used to detect complex molecules, such as explosives and drugs.

25 years later: Fixing the Hubble Space Telescope

April 24, 2015

Twenty-five years ago today, the Hubble Space Telescope was launched. The images it has been sending back to Earth for all these years have become iconic, and yet it came very close to being a billion dollar failure. One of the heroes who rescued Hubble from ruin and made it a great science success story is Rochester optics professor Duncan Moore.

Wearable technology can help with public speaking

Wearable technology can help with public speaking

March 30, 2015

Speaking in public is the top fear for many people. Now, students and faculty from the Human-Computer Interaction Group have developed an intelligent user interface for “smart glasses” that gives real-time feedback to the speaker on volume modulation and speaking rate, and have made the tool freely available for downloading.
