Electrically Driven Topological Laser Bypasses Manufacturing Imperfections
SINGAPORE, Feb. 19, 2020 — Researchers from Nanyang Technological University (NTU Singapore) and the University of Leeds (UL) have created what they believe to be the first electrically driven topological laser. The new device has the ability to route light particles around corners. The use of topologically protected photonic modes enables this laser to efficiently bypass manufacturing defects as well as corners. In the 1980s, scientists found that electrons flowing in certain materials had “topological
Breakthrough in Terahertz Quantum Cascade Lasers
LEEDS, England, Feb. 13, 2020 — A research team from the University of Leeds and the University of Nottingham believe they have found a way of delivering ultrafast modulation, by combining the power of acoustic and lightwaves. They published their findings in Nature...
Glass Doped with Erbium Could Be Used for Optical Circuits
LEEDS, England, Aug. 8, 2018 — A material created by doping glass made from zinc, sodium, and tellurium with the rare-earth element erbium could be used for broadband planar waveguide amplifiers. Scientists have started testing planar waveguides for use in signal transmission in...
Merck, University of Leeds to Collaborate on Liquid Crystal Technologies
DARMSTADT, Germany, May 30, 2017 — Science and technology company Merck KGaA has signed a five-year research collaboration agreement with the University of Leeds to develop new digital optical applications with liquid crystals. ”The University of Leeds is an ideal partner for...
Optical Glucose Sensor on Commercial Path
LEEDS, England, July 17, 2015 — A University of Leeds spin-out company is seeking to commercialize an optical glucose sensor that could make finger-prick blood tests unnecessary for people with diabetes. Glucosense Diagnostics Ltd. intends to make tabletop and wearable versions of...
Second Light Source Primes Semiconductors to See IR
LEEDS, England, and ATLANTA, April 14, 2014 — Traditional semiconductors may just need a little help to see the (IR) light.
THz Laser Chip Sets Power Records
LEEDS, England, Feb. 19, 2014 — A newly developed terahertz laser chip is already setting records as the most powerful in the world.
Satellites, Remote Sensors Shed Light on Subterranean Structures
Jun 17, 2011 — We all know that the lost city of Tanis is “one of the possible resting places of the Lost Ark” … those of us, anyway, who grew up thrilling to the exploits of the swashbuckling academic Indiana Jones. But now archaeologists may...
T-rays produced by quantum cascade laser
PARIS – For the first time, terahertz rays, or T-ray pulses, have been made to emit separate “packets” of terahertz radiation – rather than one continuous beam – from a quantum cascade laser. The finding could open new doors for...
Solar power pack lightens load for military ops
SWINDON, UK – With the aim of being up to 50 percent lighter than conventional chemical battery packs used by British infantry, the system is being developed by the University of Glasgow in collaboration with the universities of Loughborough, Strathclyde, Leeds,...
Asylum Research to Take AFM on Tour
SANTA BARBARA, Calif., Oct. 21, 2010 — Asylum Research, a manufacturer of scanning probe and atomic force microscopy (SPM/AFM) equipment, has announced that it will conduct a tour throughout the UK and Ireland over the coming months to bring its Cypher AFM to leading universities across...
THz Semiconductor Laser Revealed
CAMBRIDGE, Mass. & LEEDS, England, Aug. 10, 2010 — Applications in terahertz science and technology may be getting a boost thanks to a new terahertz (THz) semiconductor laser that emits beams with a much smaller divergence than conventional THz laser sources. The metamaterial patterns are...
A new twist on moving matter with light
ANN ARBOR, Mich. – Light can bend rigid structures, at least on a microscopic scale, researchers report. Light-driven twisting of tiny ribbons could someday be used for negative refractive index materials, in microelectromechanical systems (MEMS), or for lithography...
Asylum’s Band Excitation Technique Grants Awarded
SANTA BARBARA, Calif., March 29, 2010 — Asylum Research, manufacturer of scanning probe and atomic force (SPM/AFM) microscopes, has announced eight new grants for early adopters to explore the capabilities and applications of a new band excitation (BE) technique. The R&D100...
T-Ray Science, ULeeds Collaborate
VANCOUVER, B.C., Feb. 11, 2010 – T-Ray Science Inc. has entered into a research collaboration with the University of Leeds in the UK to develop low-cost, pulsed and continuous wave (CW), fiber-coupled terahertz (THz) spectrometers that operate at telecom wavelengths. The commercial...
UV Light Cuts TB Spread
LONDON, March 17, 2009 – Installing simple ultraviolet C (UVC) lights in hospitals could help reduce the transmission of tuberculosis, including the drug-resistant strains, by 70 percent, according to a study led by Imperial College London.
Terahertz Laser Diodes Display Single-Mode Operation
Jul 1, 2004 — Researchers at the National Enterprise for nanoScience and nanoTechnology and Scuola Normale Superiore, both in Pisa, Italy; and at Cambridge University and at the University of Leeds, both in the UK, have fabricated distributed feedback quantum...
