MIT researchers may have found a way to overcome a key barrier to the advent of super-fast quantum computers, which could be powerful tools for applications such as code breaking. Ever since Nobel Prize-winning physicist Richard Feynman first proposed the theory of quantum computing more than two decades ago, researchers have been working to build such a device.
Taiwan's sales of new energy-efficient lights soared during the first half of this year, helped by the Beijing Olympics and higher energy prices that are encouraging the use of lower-cost lighting. Taiwan's light-emitting diode (LED) makers reported that their sales rose 16.1 percent in the first half of this year from the same period a year earlier.
QD Vision, developer of nanotechnology-based solutions for displays and lighting, will address three major upcoming conferences on advances made in quantum dot technology that result in major improvements in color quality, brightness and efficiency for the solid state lighting and display industries.
The LSST, or Large Synoptic Survey Telescope, a large survey telescope being built in northern Chile, requires three large mirrors to give crisp images over a record large field of view. The two largest of these mirrors are concentric and fit neatly onto a single mirror blank. The single-piece primary and tertiary mirror blank emerged from the oven at the University of Arizona’s Steward Observatory Mirror Lab in Tucson, AZ, where team members gathered to celebrate this major milestone.
Bookham, Inc., a provider of optical components for industrial applications, has launched a single emitter-based pump laser module capable of delivering 20W of fiber coupled power into a 105um, 0.15NA fiber. The product is designed to target fiber laser and direct systems for material processing applications, and will allow laser manufacturers to optimize their dollar per watt ratio.
Andor Technology plc (Andor), a world leader in scientific imaging and spectroscopy solutions, announced today that it has signed a global supply agreement with CoolLED Ltd. to integrate the company's PrecisExcite® LED light source for fluorescence microscopy in its own range of microscopy systems. This will allow scientists to perform their research with an efficient, stable and bright light setting.
At Ferdinand-Braun-Institute (FBH) in Berlin LayTec's EpiCurve®TT HR (High Resolution) sensor is successfully used to optimise the external quantum efficiency and the emission wavelength of LEDs for near UV spectral region. Dr. Arne Knauer and co-workers apply the sensor for monitoring of composition of AlGaN and InAlGaN barrier layers.
In collaboration with Fraunhofer Institute for Photonic Microsystems (IPMS) in Dresden, Germany, LayTec has adopted its spectral reflectometer EpiR DA to an OLED in-line evaporation system to monitor UV-VIS reflectivity spectra of individual layers during production process.
Vitex, leader in thin film encapsulation and Novaled, leader in highly efficient long lifetime OLEDs (organic light emitting diodes), are going to combine advantages of the Vitex Barix thin film technology with the Novaled doping technology and materials targeting very thin and high efficiency long lifetime OLED products.
Advanced Analogic Technologies, Inc., a developer of power management integrated circuits for communications, computing and consumer electronics devices, announced today two new additions to its growing family of high current White LED (WLED) flash drivers. Supporting either two WLEDs at up to 750 mA each or one WLED at up to 1.5A and coming in a compact 3x3-mm TDFN package, the AAT1271 and AAT1272 dual-channel boost converters are the first devices of their type in AnalogicTech's WLED driver product line to feature the company's proprietary AS(2)Cwire and industry-standard I(2)C interface respectively.
