New research results from the Niels Bohr Institute show that light sources can be made much faster by using a principle that was predicted theoretically in 1954. The results are published in the scientific journal,Physical Review Letters.Researchers at the Niels Bohr Institute are working with quantum dots, which are a kind of artificial atom that can be incorporated into optical chips. In a quantum dot, an electron can be excited (i.e. jump up),...

World-leading nanoelectronics research centre imec presents at OFC 2016, the international event for both the science and business of optical communications held March 20-24th, performance improvements of various key building blocks of its wafer-scale integrated silicon photonics platform (iSiPP).

Quantum computers have significant potential to open entirely new directions for processing information and to overhaul the way that we think about and use the science of computation. Modern computers already play a huge role in society — they routinely handle and process vast amounts of data and solve calculations at an incredible rate. However, there are some problems that they just cannot solve in a useful amount of time, no matter how f...

Researchers have investigated the optical properties of the firefly's light-emitting cuticle, which is not smooth like most human-made lights, but instead is patterned with tiny hierarchical structures. Inspired by these features, the researchers replicated the patterns to create a bioinspired OLED, resulting in a 60% increase in the light extraction efficiency and 15% wider angle of illumination.

LASER World of PHOTONICS CHINA 2016, Asia’s leading laser and photonics trade show, closed at Shanghai New International Expo Centre on March 17. 802 exhibitors from 20 countries exhibited at this year’s trade show, an increase of 12% compared with 2015. The exhibition area was a record-breaking 42,000 square meters, receiving 45,528 trade visitors, up 13% on 2015. With the increasing use of laser and photonics technology in diverse s...

RMIT University researchers have trialled a quantum processor capable of routing quantum information from different locations in a critical breakthrough for quantum computing. The work opens a pathway towards the "quantum data bus", a vital component of future quantum technologies.

Scientists succeeded in integrating a laser with an organic gain medium on a silicon photonic chip. This approach is of enormous potential for low-cost biosensors that might be used for near-patient diagnosis once and without any sterilisation expenditure similar to today's strips for measuring blood sugar. The researchers now present the new laser in Nature Communications.

A group of scientists from ITMO University, in Saint Petersburg, has developed a novel approach to the construction of quantum communication systems for secure data exchange. The experimental device based on the results of the research is capable of transmitting single-photon quantum signals across distances of 250 kilometers or more, which is on par with other cutting edge analogues. The research paper was published in the Optics Express journal...

Quantum physics has moved from theoretical thought experiments to becoming a reality in advanced laboratories, and the next step is to develop quantum technology for commercial use, such as quantum information technology. In a major effort to translate quantum physics into practical quantum technology, the Danish Innovation Fund has invested 80m kr. in a nationwide project involving three universities.

Researchers from the University of Illinois at Urbana-Champaign have demonstrated an approach to modifying the light absorption and stretchability of atomically thin 2D materials by surface topographic engineering using only mechanical strain. The highly flexible system has future potential for wearable technology and integrated biomedical optical sensing technology when combined with flexible light-emitting diodes.
