Electronic chips heal after laser blasts
PASADENA, Calif. – A new self-healing integrated chip could recover in microseconds from problems ranging from low battery power to total transistor failure. Engineers at California Institute of Technology demonstrated this self-healing capability in tiny power amplifiers. They destroyed parts of the amplifiers’ chips by zapping them multiple times with a high-power laser, then saw the chips develop work-arounds in under a second. “It was incredible the first time the system kicked in and...
FAMOS aims to make OCT light sources more compact
VIENNA – Optical coherence tomography light sources will shrink to one-fifth the size of conventional devices with the help of a tapered laser being developed by the European Union project FAMOS (Functional Anatomical Molecular Optical Screening). ...
Flex-grid prevents network traffic jams
BARCELONA, Spain – A flexible-grid system that controls connections in optical networks can also redirect traffic to other networks, avoiding gridlock. Similar to how services like Google Maps use algorithms to determine the fastest route from point A to point...
Glasses-free 3-D could be coming to a mobile display near you
PALO ALTO, Calif. – While developing optical interconnect technology, engineers at Hewlett-Packard Laboratories realized what they had created could be much more: a multiangle, glasses-free 3-D display technology for mobile devices. Dr. David Fattal is a member of...
Landmark Ireland research investment includes photonics
DUBLIN – The largest-ever state/industry co-funded scientific research investment in Ireland – €300 million – includes millions to establish a large-scale research center devoted to advancing photonics and biomedical science. The...
Metamaterials observe photonic spin Hall effect
BERKELEY, Calif. – A metamaterial surface constructed of V-shaped gold nanoantennas was used to obtain the strongest signal yet of the photonic spin Hall effect – a quantum mechanical optical phenomenon that could play a prominent role in the future of...
New metamaterials are easily manufactured
UNIVERSITY PARK, Pa. – By combining theory and practice, two groups of Penn State scientists have designed low-loss optical metamaterials that are easily manufactured for custom applications with dispersions that can be tuned over large bandwidths. Designing...
Novel use of EMCCD sharpens images
DALLAS – Sharper microscopic images may be in sight with a new method that uses standard low-light electron multiplying CCD (EMCCD) cameras in a new way to reduce noise and minimize image deterioration. Conventional imaging can add electronic noise,...
Plasmonics help ‘bulk’ silicon emit visible light
PHILADELPHIA – A commonly used form of silicon has been made to emit broad-spectrum, visible light, but challenges remain before it can form practical electronic-photonic devices. As engineers move ever closer to the limits of electronic circuits, light is...
Printable library makes one-of-a-kind optics affordable
HOUGHTON, Mich. – Inspired by the need for optics used in a specialized tool for photovoltaic research, a professor at Michigan Technological University has created an open-source optics library that is gaining popularity around the world. “We want to...
Future Looks Sunny for Organic Polymers
HOUSTON, and UNIVERSITY PARK, Pa., May 30, 2013 — Solar cells based on block copolymers, self-assembling organic materials that arrange themselves in distinct layers, could pave the way for a new class of solar energy devices.
Light-Sensitive Material Promising for 3-D Shaping
YOKOHAMA, Japan, May 30, 2013 — A light-sensitive resin that responds to the process of “carbonizing,” or charring, could provide scientists with a new material that can be molded into complex, highly conductive 3-D structures with features just a few microns across. The findings...
Light Coupled in Fiber Oscillates Longitudinally
VIENNA, May 29, 2013 — Lightwaves, which typically oscillate perpendicular to their propagation direction, have been seen oscillating longitudinally when coupled into glass fibers, suggesting that light and matter couple much more strongly than previously thought.
Cradle Turns Smartphone into Biosensor
CHAMPAIGN, Ill., May 28, 2013 — A unique cradle and app for the iPhone use the phone’s own camera and processing power to create a handheld biosensor capable of detecting any kind of biological molecules or cells.
Old Imaging Technique Gets Quality Boost
PERTH, Australia, May 28, 2013 — Targeting crosstalk problems — visible ghostlike shadows in 3-D images — could significantly increase the quality of a widely used century-old printing technique, new research out of Australia suggests.
University of Eastern Finland Opens Photonics Institute
JOENSUU, Finland, May 28, 2013 — A new Institute of Photonics launched at the Faculty of Science and Forestry of the University of Eastern Finland aims to enhance education and research in photonics and to promote international collaboration in the field.
Laser-Printed Air Tube Saves Baby’s Life
ANN ARBOR, Mich., May 24, 2013 — A baby boy can now breathe easy thanks to a 3-D-printed tracheal splint implant developed at the University of Michigan.
Spray-On Flat Lens Works in the UV
GAITHERSBURG, Md., May 24, 2013 — A metamaterial-based flat lens that’s easy to fabricate and that can bend and focus UV light could improve photolithography, nanoscale manipulation and manufacturing, and even high-resolution 3-D imaging, say scientists at the National...
IEEE Offers Open-Access Option for All Peer-Reviewed Journals
PISCATAWAY, N.J., May 23, 2013 — Driven by member and author feedback, technical professional association IEEE has announced that all of its peer-reviewed journals — more than 100 — now offer open-access publishing options.
Method Creates Atomic-Scale Semiconductors
RALEIGH, N.C., May 23, 2013 — An inexpensive material that can be “grown” in layers only one atom thick has yielded atomic-scale semiconductor thin films. The technique could be applied to make these devices wide enough to coat wafers that are 2 in. wide or larger.
Photonics Societies Launch National Initiative
WASHINGTON, May 23, 2013 — The National Photonics Initiative — an alliance seeking to unite experts from industry, academia and the government to advance photonics R&D, to grow the US economy, and to improve national security — officially launched today.
Transparent Electrode Key to Flexible Solar Cells
WEST LAFAYETTE, Ind., May 23, 2013 — A hybrid transparent electrode that overcomes the “electron-transport bottleneck” of thin films could pave the way for flexible solar cells and color monitors, head-up displays in car windshields and optoelectronics circuits for sensors and...
Controlling Light … with Light
HOUSTON, May 22, 2013 — Gold nanoparticles arranged into geometric patterns can control incoming light with light via a four-wave mixing process, transforming its output into a different color, Rice University theoretical and applied physicists say. The technique could be...
Nanoantennas Improve Infrared Sensing
PHILADELPHIA, May 21, 2013 — Patterning nanoantennas with “slots” that correspond to wavelengths in the mid-IR has yielded a new way to tune IR light into mechanical action, paving the way for more sensitive IR cameras and more compact chemical-analysis techniques....
Optical Chip Innovation Transferred to Industry
SYDNEY, May 21, 2013 — An optics innovation that enables researchers to vary how light is split on optical chips has been transferred from the University of Sydney to Finisar, creating a wave of sales for the Waterloo, Australia-based company.
