Programmable Device Enables Optical Control at Unprecedented Speeds
CAMBRIDGE, Mass., Nov. 30, 2022 — An international team led by MIT researchers has developed a spatial light modulator (SLM) that promises greater control of light at orders of magnitude more quickly than commercial devices. The team also developed a fabrication process to ensure consistent device quality when manufactured at scale. The device could be used to create superfast lidar sensors for self-driving vehicles that could image a scene about a million times faster than existing mechanical systems. It could also be
Light-Driven Microdrones Offer Nanosensing, Motion Possibilities
WÜRZBURG, Germany, April 26, 2022 — Physicists at the University of Würzburg have used light to propel micrometer-size objects in an aqueous environment and control them precisely on a surface with all three degrees of freedom — two translational degrees and a rotational...
Tunable Nanophotonic Interface Simplifies PIC Integration
CHICAGO, March 22, 2022 — A chiral nanophotonic interface developed by a research team at the University of Chicago could make photonic integrated circuits (PICs) easier to integrate into mapping systems, biosensors, and other technologies. The interface provides a way for...
Active Substance Optically Manipulates Component of Cytoskeleton
JENA, Germany, May 22, 2020 — An international research team from Jena, Munich, and New York has used photopharmacology — the use of light to switch the effect of drugs on and off — to control actin, a component of cells that was previously considered inaccessible....
Metamaterial Can Change Optical Properties, Become Invisible or Reflective in IR Spectrum
ST. PETERSBURG, Russia, May 21, 2020 — Researchers at ITMO University and the University of Exeter have developed a metamaterial capable of changing its optical properties without any mechanical input. The new metamaterial could improve the reliability of complex optical devices while...
Liquid Crystal Matrix Slows Light to 1 Billionth of its Speed
NICE, France, and XIAMEN, China, Aug. 14, 2013 — Light can be slowed to less than a billionth of its top speed by using embedded dye molecules in a liquid crystal matrix, which could lead to new technologies in remote sensing and measurement science. Taking advantage of light’s travel as a...
Plasmon waves control light
CAMBRIDGE, Mass. – A nanoscale coupler that converts optical signals into surface plasmon polaritons can distinguish between different movements of polarized light and can precisely manipulate the signals in one direction or another without damaging them. The device...
’Temporal Cloaking’ for Communications
WEST LAFAYETTE, Ind., June 5, 2013 — An alternative “temporal cloaking” method that uses standard optical communications components has improved the time available for secure data transmission to nearly 46 percent, allowing digital data to be concealed at rates that could thwart...
Plasmon Waves Control Light
CAMBRIDGE, Mass., April 23, 2013 — A nanoscale device that converts optical signals into surface plasmon polaritons can distinguish between different movements of polarized light and precisely manipulate the signals in one direction or another without damaging them.
Metamaterials manipulate light on a microchip
UNIVERSITY PARK, Pa. – Controlling light on a microchip is no easy feat, but new theoretical designs for miniaturized optical devices made of metamaterials could make it a little easier. A unified theory from researchers at Penn State University combines metamaterials and...
Metamaterials Manipulate Light on a Microchip
UNIVERSITY PARK, Pa., Nov. 28, 2012 — Controlling light on a microchip is no easy feat, but new theoretical designs for miniaturized optical devices made of metamaterials may provide a solution.
Silicon could enable mass production of quantum computing
BRISTOL, UK – A new silicon-based approach to quantum computing could make the technology easier to mass-produce. Scientists at the University of Bristol’s Centre for Quantum Photonics, leading an international collaboration, made the leap from glass-based...
A Silicon-Based Approach to Quantum Computing
BRISTOL, England, Sept. 6, 2012 — A new silicon-based approach to quantum computing could make the technology easier to mass-produce. Scientists at the University of Bristol’s Centre for Quantum Photonics, leading an international collaboration, made the leap from glass-based...
Loops of Light Optically Detect Single Molecules
LEUVEN, Belgium, July 19, 2012 — A new nanoscale light-manipulation method that optically detects single molecules could be used in a variety of photochemistry applications and could help advance technologies for visualizing single molecules and multiple-molecule interactions.
Postage-stamp-sized Displays Move Closer
ANN ARBOR, Mich., Oct. 14, 2010 — University of Michigan scientists using AFOSR-funding have created the smallest pixels available that will enable LED, projected and wearable displays to be more energy efficient with more light manipulation possible and all on a display that may...
