Topology-Based Fiber Ensures Robust Performance Amid Distortions
BATH, England, March 17, 2023— Researchers at the University of Bath fabricated optical fiber that hosts topological supermodes across multiple light-guiding cores. The topological protection of the fibers prevents changes to the structure of the fiber edge modes when the intercore coupling — or how much light can move between each core — changes, such as in the event of a bend or twist. The fabrication approach targets the need for optical fibers that comprise a network to traverse natural
Ring Resonator Pushes Photonic Sensing to Quantum Limit
BRISTOL, England, June 9, 2022 — A team led by researchers at the University of Bristol developed a method for operating mass manufacturable photonic sensors at the quantum limit. The work paves the way for practical applications, including the monitoring of greenhouse gas...
Hollow-Core Optical Fibers Offer Advantages at Any Wavelength
Feb 25, 2019 — Conventional optical fibers are fabulously successful, but they have profound limitations. These include a finite spectral transparency, susceptibility to optical damage, dispersion — which restricts the ability to deliver short and ultrashort...
University of Bath Receives €4M EU Award for Photovoltaic Initiatives
BATH, England, July 3, 2018 — Research and development of a new and potentially low-cost class of solar materials has been given €4 million ($4.6 million) in funding by the European Commission with the establishment of a new research training network led by the University...
Gold Spring-Shaped Coils and Lasers Detect Twisted Molecules
BATH, England, April 10, 2017 — A novel technique that uses powerful lasers and gold spring shaped coils 5,000 times thinner than human hair could improve pharmaceutical design, telecommunications and nanorobotics, as it has the ability to detect twisted molecules. Molecules twist...
Fiber Optics Help Improve the Performance of Single-Photon Sources
BATH, England, Nov. 29, 2016 — Information can be imprinted on single photons that can in turn, perform calculations and transmit messages. Creating the “individual” photon to do that is a complicated and challenging process though. With the help of fiber optics and...
Fianium Awarded R&D Projects Worth $2.1M
SOUTHAMPTON, England, Oct. 20, 2013 — Fianium was recently awarded three research and development projects by the UK government worth approximately £1.35 ($2.1 million) to develop its ultrafast and supercontinuum fiber lasers for high-volume industrial and medical applications,...
Outlook bright for UK manufacturing
SWINDON, England – The future of manufacturing in the UK has just gotten a little brighter: The Engineering and Physical Sciences Research Council (EPSRC) has awarded six grants totaling £12.2 million to four new research centers that promise to improve...
UK Health Care Investment Includes Fiber Optics
EDINBURGH, Scotland, and SWINDON, England, May 10, 2013 — The development of fiber optic sensors that monitor the condition of intensive care patients is among the projects that will benefit from a £32 million (about $49 million) investment, the Engineering and Physical Sciences Research Council...
Outlook Bright for UK Manufacturing
SWINDON, England, March 1, 2013 — The future of manufacturing in the UK has just gotten a little brighter: The Engineering and Physical Sciences Research Council (EPSRC) has awarded six grants totaling £12.2 million (about $18 million) to projects promising to improve...
Lasers Simulate Black Hole Radiation
COLLEGE PARK, Md., Nov. 10, 2010 — A team of Italian scientists has fired a laser beam into a chunk of glass to create what they believe is an optical analogue of the Hawking radiation that many physicists expect is emitted by black holes. Although the laser experiment superficially...
Photon Color Barrier Broken in Fiber
EUGENE, Ore., Oct. 6, 2010 — The color of single photons in a fiber optic cable has been changed for the first time. The laser-tweaked feat could be a quantum step forward for transferring and receiving high volumes of secured data for future generations of the Internet.
Soliton Milestone Achieved
WASHINGTON, DC, Nov. 21, 2008 – Since the 1980s, dispersive waves have been studied in the concept of solitons (waves that maintain their shape while traveling at constant speeds). Now, a research team led by Fetah Benabid, University of Bath, has observed for the first time the...
Supercontinuum Fiber Lasers
SOUTHAMPTON, UK and EUGENE, Ore. Oct. 14, 2008 – A consortium led by ultrafast fiber laser manufacturer Fianium Ltd., is to develop and evaluate advanced white-light (supercontinuum) fiber lasers for biomedical imaging applications. The $3.6 million "WhiteLase" project is co-funded by the UK...
UBath Nanotech Facility Free for UK University Researchers
Nov 16, 2007 — Scientists and engineers from UK universities will be allowed free use of the University of Bath's nanotechnology facilities to assist their research, the university announced this week. The David Bullett Nanofabrication Facility will be set aside...
Mass-Marketed OLEDs Could Power Lighting Revolution
BATH, England, April 19, 2007 -- A thin film of plastic that conducts electricity and produces solar power could be the basis for a revolution in the way we light our homes and design clothes. An international research project has begun that could help bring to mass-market organic...
Waveform Project May Advance Photonic Computers
BATH, England, March 14, 2007 -- The dream of photonic computers -- devices run using light rather than electronics -- could be nearing our desktops. Physicists at the University of Bath will be looking at developing attosecond technology -- the ability to send out light in a...
Highly Birefringent Fiber Has Layered Core
Dec 1, 2005 — At the University of Bath in the UK, researchers have produced an optical fiber that they believe has the highest birefringence ever reported. Birefringent fibers are important in applications where the polarization of light that is traveling...
The Picture of Health
Dec 1, 2005 — Researchers at the University of Bath in the UK are investigating a therapy in which patients look in a mirror to ease pain. They are operating on the theory that the brain’s image of the body can become faulty, mismatching movement control and...
Gas Sample Cell Based on Photonic Bandgap Fiber
May 1, 2005 — By splicing a single-mode fiber to each end of a gas-filled, hollow-core, photonic bandgap fiber, researchers at the University of Bath in the UK have created a gas cell with unprecedented interaction efficiency between the sample and light. They...
High-NA Fibers Enable High-Power Lasers
May 1, 2004 — A research group at the University of Bath in the UK has analyzed and demonstrated techniques to fabricate photonic crystal fibers (PCFs) with a numerical aperture as high as 0.9. The techniques may dramatically affect the efficiency and power of...
Photonic Bandgap Fiber Eyed for Telecommunications
Apr 1, 2004 — Researchers at BlazePhotonics Ltd. and at the University of Bath, both in Bath, UK, have fabricated a new low-loss photonic bandgap fiber. Its attenuation of 1.72 dB/km represents a significant improvement over the lowest loss previously reported...
