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)
New magnets with 99% air content
Researchers from the Physics Department at the Universitat Autònoma de Barcelona (UAB), the Institut de Cie'nca de Materials de Barcelona (ICMAB-CSIC), and the Universidad de Zaragoza have created a new ultra-light transparent magnetic material. Thanks to its properties, the new material could have interesting technological applications,... view more... (2003-11-25)
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)
Using invisibility to increase visibility
Research into the development of invisibility devices has spurred two physicists' thought on the behaviour of light to overcome the seemingly intractable problem of optical singularities which could soon lead to the manufacturing of a perfect cat's eye. view more (2008-12-01)
NIST releases new standard for semiconductor industry
A wide range of optical electronic devices, from laser disk players to traffic lights, may be improved in the future thanks to a small piece of semiconductor, about the size of a button, coated with aluminum, gallium, and arsenic (AlGaAs). view more (2006-10-13)
Scientists at the University of the Basque Country succeed in cooling solid material with laser
A team of researchers at the University of the Basque Country (UPV/EHU) have experimentally demonstrated something that other scientists have been trying to achieve for decades: the cooling of erbium-doped materials with laser light. view more (2006-07-27)
raGraphene and gallium arsenide: two perfect partners find each other
It is the marriage of two top candidates for the electronics of the future, both excentric and extremely interesting: Graphene, one of the partners, is an extremely thin fellow and besides, very young. view more (2009-09-17)
Light turns liquid
LIGHT can be turned into a glowing stream of liquid that splits into droplets and splatters off surfaces just like water. The researchers who`ve worked out how to do this say "liquid light" would be the ideal lifeblood for optical computing, where chips send light around optical "circuits" to process data. Liquid light sounds like a... view more... (2002-07-03)
Butterflies' wings dazzle with science
The brilliant dazzle of butterflies' wings could hold the key to a new type of optical material, called photonic crystals. Over the past 15 years, photonic crystals have attracted the attention of a vast international community, as scientists have begun to realise their potential applications in the field of optoelectronics and telecommunications.... view more...

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)
Guiding light - CMD19/CMMP with The Physics Congress 2002
A new type of optical material has been developed by physicists that could replace the electronics used to route the light signals through optical fibre telecommunications networks. It could even provide the basis for future `optical computers` working on light pulses instead of electric signals. At the Condensed Matter conference on Monday 8... view more... (2002-03-26)
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)

Researchers bend light through waveguides in colloidal crystals
Researchers at the University of Illinois are the first to achieve optical waveguiding of near-infrared light through features embedded in self-assembled, three-dimensional photonic crystals. view more (2008-01-08)
Optical refrigeration expected to enhance airborne and spaceborne applications
Under an Air Force Office of Scientific Research, multi-university grant, a team led by University of New Mexico professor, Dr. Mansoor Sheik-Bahae created the first-ever all-solid-state cryocooler that can be applied to airborne and spaceborne sensors. view more (2010-02-01)
ORMatE returns to NRL after nearly 2 years in Earth orbit
Completing an 18-month mission orbiting the Earth more than 6,000 times on-orbit the International Space Station (ISS), the Optical Reflector Material Experiment (ORMatE-1) returns to Washington, D.C., to NRL's Electronics Science and Technology Division to begin experiment testing and analysis. view more (2009-09-30)
Custom-sized microlenses
Optical components have joined the trend towards miniaturization. There have, however, been no methods available thus far to produce custom-sized glass lenses. A new process now enables the low-cost, high-volume manufacture of microlenses with extreme dimensions. view more (2004-08-27)
Pitt and Bell Labs researchers send 'heavy photons' over world-record distances
When light hits a semiconductor material and is absorbed, its photons can become "excitons," sometimes referred to as "heavy photons" because they carry energy, like photons, but have mass, like electrons. view more (2005-06-22)
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)
New hybrid microscope probes nano-electronics
A new form of scanning microscopy that simultaneously reveals physical and electronic profiles of metal nanostructures has been demonstrated at JILA, a joint institute of the National Institute of Standards and Technology (NIST) and University of Colorado at Boulder. view more (2006-10-30)
