The ultra-high data speeds possible on optical fibre networks will only come into their own when the fibres reach the last mile into everyone’s home. But that will require miniaturisation and integration of optical components on a scale not yet seen. European researchers may have some of the answers. Broadband access has transformed the economic potential of the internet.
A team of researchers at the University of St. Andrews has developed one of the smallest optical switches ever made.
Photonic Products, the UK optoelectronics device manufacturer and laser diode specialist, has announced the introduction of two new, high power, infrared wavelength GaAlaS laser diodes from Opnext, Inc. The HL8337MG and the HL8338MG are ideal as light sources for industrial and medical sensor applications and as a light source for various other types of optical equipment such as distance meters, barcode scanners and high resolution CTP.
Complex three-dimensional (3D) integrated circuits involving both optical and electronic elements are now easier to make, thanks to a “wafer bonding” technique developed by a European research consortium. With the right commercial backing, the new technology will help Europe stay competitive in communications and sensor technology.
The market for organic electronics materials will be worth $4.9 billion in 2012 surging to $15.8 billion in 2015, according to a new report from NanoMarkets, an industry analyst firm based here.
What are the defining discoveries and great developments that are shaping the way we use materials and technologies today? Elsevier¡¦s Materials Today magazine has compiled a list of the top ten most significant advances in materials science over the last 50 years.
Last year researchers from Duke University stunned the world when they announced a cloaking device for the microwave range. This device made use of metamaterials that had a negative refractive index for electromagnetic radiation. The metamaterials were carefully designed split-ring resonators with a structure size much smaller than the wavelength. Only 10 stacked layers of metamaterials were necessary to achieve the desired invisibility effect.
The dashing start of electrons in a crystal does not remain without consequences for their further fate. This is reported by the Berlin researchers Peter Gaal, Wilhelm Kuehn, Klaus Reimann, Michael Woerner, and Thomas Elsaesser of the Max-Born Institute and Rudolf Hey of the Paul Drude Institute in the latest issue of the magazine Nature (Vol. 450, Page 1210).
Raytheon Company achieved a significant milestone on the Zumwalt-class destroyer program with the successful design review of the ship's electro- optical/infrared (EO/IR) system. With this success, the U.S. Navy has given Raytheon Integrated Defense Systems approval to advance the design into the production phase.
The new LabMax laser power and energy meter from Coherent, Inc. supports position sensing detectors, and is compatible with all the company’s current and past sensors. Position sensing simplifies proper alignment with the detector, thus ensuring measurement accuracy, and also permits long term beam monitoring.
