High resolution detectors to create safer X-ray diagnosis
With over 22 million X-rays being recorded in the NHS in England last year, they are a diagnostic test that most of us are familiar with. Scientists have often sought to reduce harmful ionising radiation, the high-energy particles that penetrate tissue to reveal internal organs and bone structures that can damage DNA, from single x-ray records or CT scans.Although this ionising radiation can be reduced, traditionally it has come at the expense of...

Environmentally-friendly graphene textiles enable wearables
A method for producing conductive cotton fabrics using graphene-based inks opens up new possibilities for flexible and wearable electronics, without the use of expensive and toxic processing steps.Wearable, textiles-based electronics present new possibilities for flexible circuits, healthcare and environment monitoring, energy conversion, and many others.
Alternative storage concepts for better quantum memories
Conventional memories used in today’s computers only differentiate between the bit values 0 and 1. In quantum physics, however, arbitrary superpositions of these two states are possible. Most of the ideas for new quantum technology devices rely on this “Superposition Principle”. One of the main challenges in using such states is that they are usually short-lived. Only for a short period of time can information be read out of qua...
Passive and active devices on show at micro photonics in Berlin
This year’s micro photonics will see the Fraunhofer Heinrich Hertz Institute HHI presenting its latest solutions of photonic components. Fraunhofer HHI enables an own design of InP-based Photonic Integrated Circuit (PIC) containing passive and active devices on one substrate. It is possible to choose from a range of proven building blocks, such as 40GHz receivers, 20GHz transmitters, and 1dB/cm passive waveguides.
Laser World of Photonics 2017: the future of technology
The world’s leading trade fair LASER World of PHOTONICS, from June 26 to 29, 2017 in Munich is setting new records: more than 1,250 exhibitors are anticipated, occupying 55,000 square meters of exhibition space to present visitors from around the world their ideas for the future of optical technologies. Right next door, leading researchers and industrial practitioners will be meeting for a technical dialog at the World of Photonics Congress...
Solar smart window offers privacy and light control
Smart windows get darker to filter out the sun's rays on bright days, and turn clear on cloudy days to let more light in. This feature can help control indoor temperatures and offers some privacy without resorting to aids such as mini-blinds. Now scientists report a new development in this growing niche: solar smart windows that can turn opaque on demand and even power other devices. The study appears in ACS Photonics.
Wearable THz scanning device for medical applications
Scientists at Tokyo Institute of Technology have developed a portable and wearable terahertzscanning device made using arrays of carbon nanotubes, for non-invasive inspection of three-dimensional objects without requiring bulky peripheral optical components. The device is expected to have wide ranging applications including the noninvasive inspections of medical and drug delivery equipment such as syringes, as well as in medicine for imaging canc...
Rapid allergy detector to beat penicillin deaths
Sufferers of hypersensitivity to common antibiotics like penicillin and amoxicillin will soon find help with a new allergy detector, a low-cost, bio-photonic device that will provide more targeted treatment for millions of patients.
Developing single device with wide range of optical capabilities
Scientists at the Department of Energy's Lawrence Berkeley National Laboratory have for the first time created a single device that acts as both a laser and an anti-laser, and they demonstrated these two opposite functions at a frequency within the telecommunications band.Their findings, reported in a paper to be published in the journal Nature Photonics, lay the groundwork for developing a type of integrated device with the flexibility to operat...
