Tunable Photomemristor Streamlines Neuromorphic Vision Processing
HANGZHOU, China, Feb. 22, 2023 — Researchers at Hangzhou Institute for Advanced Study, State Key Laboratory of Infrared Physics, and Shanghai Institute of Technical Physics have created a two-terminal, nonvolatile photomemristor with a simple architecture and tunable...
Silicon Photonics Accelerates On-Chip Neural Network Training
WASHINGTON, D.C., Dec. 8, 2022 — Researchers from George Washington University (GWU) have introduced a strategy for training deep neural networks the benefits of using photonics to execute artificial intelligence (AI) applications. The team’s CMOS-compatible silicon photonics...
Efficient, Nano-Size Optical Computer Crunches Complex Data
NEW YORK, March 14, 2022 — A research team led by Andrea Alù at the City University of New York (CUNY) and Heedong Goh at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) developed a design for a nano-size, wave-based computer that solves...
Deep Learning-Trained Neural Network Reconstructs OCT Images
LOS ANGELES, Aug. 12, 2021 — A team of UCLA and University of Houston (UH) scientists, led by Aydogan Ozcan in collaboration with Kirill Larin, used deep learning to train a neural network to rapidly reconstruct OCT images using undersampled spectral data. Although the...
High-Efficiency PICs Accelerate Telecom Speeds to 40 Tbit/s
Duesseldorf, Germany, July 20, 2021 — Using multiple wavelengths to deliver information — all on a single PIC — collaborators from Dublin-based Pilot Photonics and the European photonics innovation incubator ACTPHAST 4.0 have found a way to pack more data into existing...
Nanomechanical fiber goes beyond light transmission
SOUTHAMPTON, England – A new dual-core optical fiber that can perform the functions of signal switches, routers and buffers by applying a minute amount of mechanical pressure could significantly enhance data processing and perform sensing functions in electronic devices....

3-D bow-tie nanolaser defies diffraction limit
EVANSTON, Ill. – Nanolaser devices operating at room temperature defy the diffraction limit, thanks to a lasing cavity composed of 3-D bow-tie-shaped metal nanoparticle dimers designed by researchers at Northwestern University. The diffraction limit has been a...
Nanomechanical Fiber Goes Beyond Light Transmission
SOUTHAMPTON, England, Dec. 19, 2012 — A new dual-core optical fiber that can perform the functions of signal switches, routers and buffers by applying a minute amount of mechanical pressure could significantly enhance data processing and perform sensing functions in electronic devices.
Virus-Sized Laser Defies Diffraction Limit
EVANSTON, Ill., Nov. 6, 2012 — The bow tie is a popular shape for pasta and maybe soon it will be for lasers, too. Single-laser devices the size of virus particles operate at room temperature and defy the diffraction limit, thanks to a lasing cavity composed of 3-D bow-tie-shaped...
Spectroscopy Technique Advances Spintronics
BERKELEY, Calif., Oct. 16, 2012 — An x-ray spectroscopy technique marks a significant step toward removing a major roadblock impeding the use of certain semiconductors in computing, because processing data using electron “spin” rather than charge would mean smaller, faster and more...
Metamolecules Change Chirality Under Light
BERKELEY, Calif., July 11, 2012 — For the first time, the chirality of artificial molecules has been switched from a right-handed to a left-handed orientation using a light beam. The discovery holds potential for a range of terahertz technology applications, including biomedical...
New Laser Tech Beefs Up DVDs and Kills Viruses
RIVERSIDE, Calif., July 12, 2011 — Imagine a laser technology that could do everything from kill viruses to increase storage capacity of DVDs. Now a team from the Bourns College of Engineering at the University of California, Riverside, has made a discovery about semiconductor...
Quantum Random Number Generator Service Begins
BERLIN, Dec. 2, 2010 — PicoQuant GmbH and Nano-Optics groups at the Department of Physics of Humboldt University Berlin announced they have started a Quantum Random Number Generator (QRNG) that is based on the quantum randomness of photon arrival times. The...
Defense R&D Commands the Stage
ORLANDO, Fla., March 24, 2010 – Considered the number-one show for infrared (IR) imaging, optics and sensors, and the largest international unclassified defense-related symposium, SPIE Defense, Security and Sensing 2010 will offer attendees access to more than 2300 technical...
Freezing Time in 3-D
Jun 1, 2005 — In microscopy, researchers strive for better resolution and faster data processing. Piezoelectric positioning devices, which have been used in some form for years, can help them meet these needs. When using a piezoelectric Z-axis positioning...
