Stevens faculty release study on free-space optical communication in Optics Express
Three members of the faculty at Stevens Institute of Technology recently collaborated on a paper focusing on free-space optical communication, which appears in the latest issue of Optics Express, a premiere optics journal currently in circulation. view more (2009-03-18)
Scientists demonstrate all-fibre quantum logic
A team of physicists and engineers have demonstrated all-fibre quantum logic, where single photons are generated and used to perform the contolled-NOT quantum logic gate in optical fibres with high fidelity. view more (2009-05-29)
Hanover Trade Fair 2003: Precise positioning of optical fibres
Connector for the flexible set-up of optical communication networks Setting up low-cost optical communication networks requires suitable interfaces such as plug connectors or couplings which can position optical fibre ribbons with a very fine tolerance. Together with three cooperation partners, the Institut für Mikrotechnik Mainz GmbH (IMM)... view more... (2003-04-07)
New Optical Antenna Brings Massive Benefits to Wireless Networks, Household Electronics and Longer Distance Data Transfer
A new optical antenna, developed by researchers at the University of Warwick, will bring significant benefits to credit card payments, wireless networks, household electronics and longer distance data transfer. The device was developed by Professor Roger Green and Roberto Ramirez-Iniguez, in the University of Warwick`s Engineering Department. It... view more... (2002-11-07)
Optical Atomic Clock: A long look at the captured atoms
Optical clocks might become the atomic clocks of the future. Their "pendulum", i.e. the regular oscillation process which each clock needs, is an oscillation in the range of the visible light. view more (2008-02-06)
Researchers generate high-speed pulses of laser light on silicon, speeding data transmission
In the Sept. 3 issue of Optical Society of America's Optics Express, published online today, researchers announce that they have built the world's first "mode-locked silicon evanescent laser." view more (2007-08-22)
Another world first for Artemis: a laser link with an aircraft
Artemis, the European Space Agency Advanced Relay and Technology Mission Satellite, successfully relayed optical laser links from an aircraft in early December. These airborne laser links, established over a distance of 40 000 km during two flights at altitudes of 6000 and 10 000 metres, represent a world first. view more (2006-12-19)
Improved spectrometer based on nonlinear optics
Scientists at Stanford University and Japan's National Institute of Informatics have created a new highly sensitive infrared spectrometer. view more (2008-11-13)
Making monster waves
Rogue waves-giant waves that spring up suddenly and tower over the seas around them-have inspired physicists to look for an analogue in light. view more (2009-10-20)

Communication problems affect one in four 999 ambulance calls
Communication problems affect more than a quarter of emergency ambulance calls, finds a study in this week's BMJ. A sample of 999 calls received by West Midlands Ambulance Service and Derbyshire Ambulance Service during one week of December 1998 was assessed for communication difficulties. Of 1830 calls, 26% were associated with a communication... view more... (2001-10-03)
Computer hackers R.I.P. -- making quantum cryptography practical
Quantum cryptography, a completely secure means of communication, is much closer to being used practically as researchers from Toshiba and Cambridge University's Cavendish Laboratory have now developed high speed detectors capable of receiving information with much higher key rates, thereby able to receive more information faster. view more (2009-04-30)
Polarization holographic device using photoreactive polymer liquid crystals
Photo-control of molecular orientation of polymer materials is of great interest for the development of highly functionalized holographic optical devices. view more (2005-10-19)
UCSB researchers develop hybrid silicon evanescent laser
In what promises to be an important advance, researchers at the University of California, Santa Barbara have developed a novel laser by bonding optical gain layers directly to a silicon laser cavity. view more (2005-11-16)
Survey shows that scientists want training in communicating with the general public.
In a survey, commissioned by the Engineering and Physical Sciences Research Council, almost 60 per cent of researchers questioned said they have communicated with the general public but the majority had not received any specific training in this area. The findings of the survey coincide with an announcement that EPSRC is to offer researchers that... view more... (2002-03-21)
Hanover Trade Fair 2003: Getting to grips with optical fibres
A vacuum gripper mounts optical waveguides exactly right on the micrometre Microtechnological precision components from the production line - up to date, the realisation of this vision lacked the tools and technologies for automated manufacturing. Therefore, the aim of the research project „MELEMECH", sponsored by the federal German... view more... (2003-04-07)
Europe leads the world in science communication
European science communication experts meeting in Poland strongly urge the governments of all European nations to increase their financial and motivational support for science communication events. EUSCEA, the European Science Events Association, brings together the leaders of Science Festivals and Science Weeks from all over the continent of... view more... (2003-06-17)
A technological breakthrough for radio astronomy - Astronomical observations via high-speed data link
To carry out simultaneuos observations with several telescopes and transform the combined data into pictures from distant galaxies has so far been a cumbersome procedure which often has taken a long time. Now a breakthrough has been achieved by way of the installation of optical fibre links between the observatories and the universities who have... view more... (2004-01-26)
Can email help doctors use their time more productively?
In almost every era doctors have perceived themselves as "running faster" but there is little evidence to support this. Doctors feel stressed because there is now so much more they can do. There are more external forces impinging on their practice and patients and the public have raised expectations, yet patients value meaningful time... view more... (2001-08-01)
CT colonoscopy has 90 percent agreement rate with optical colonoscopy
Nearly 90% of colon polyps greater than or equal to 6 mm in size detected at CT colonoscopy were demonstrated to represent true polyps at subsequent optical colonoscopy (the traditional method of viewing the colon and removing precancerous growths). view more (2007-05-07)
