Super-resolution microscopy in space and time

Super-resolution microscopy in space and time
Super-resolution microscopy is a technique that can “see” beyond the diffraction of light, providing unprecedented views of cells and their interior structures and organelles. The technique has garnered increasing interest recently, especially since its developers won the Nobel Prize in Chemistry in 2014. But super-resolution microscopy comes with a big limitation: it only offers spatial resolution.

Delivering next-gen silicon photonics optical modules

Delivering next-gen silicon photonics optical modules
Rockley Photonics Limited has announced a joint venture with Hengtong Optic-Electric Co., Ltd. to manufacture high performance optical transceiver modules based on its silicon photonics technology. The joint venture (JV) was established based on a $42m co-investment led by Hengtong Optic-Electric, a world leader in the fiber-optic communication industry, and will commercialise Rockley Photonics’ advanced photonics technology for networking applications.

Boost efficiency and stability of optical rectennas

Boost efficiency and stability of optical rectennas
The research team that announced the first optical rectenna in 2015 is now reporting a two-fold efficiency improvement in the devices — and a switch to air-stable diode materials. The improvements could allow the rectennas – which convert electromagnetic fields at optical frequencies directly to electrical current – to operate low-power devices such as temperature sensors.

Optimising optics through increased design efficiency

Optimising optics through increased design efficiency
If photonics is to meet the needs of a new generation of applications, problems will need to be addressed through better design and modelling. The EU-funded ADOPSYS project approached this challenge as much with a skills-based answer, as a technical one. Currently the field of photonics suffers from a lack of broad expertise in applied modelling and design for industrial optical systems and components.

Hyperlens crystal views living cells in unprecedented detail

Hyperlens crystal views living cells in unprecedented detail
Just imagine: An optical lens so powerful that it lets you view features the size of a small virus on the surface of a living cell in its natural environment. Construction of instruments with this capability is now possible because of a fundamental advance in the quality of an optical material used in hyperlensing, a method of creating lenses that can resolve objects much smaller than the wavelength of light.

Imaging technique reveals the secrets of 17th century paintings

Imaging technique reveals the secrets of 17th century paintings
The secrets of 17th century artists can now be revealed, thanks to 21st century signal processing. Using modern high-speed scanners and the advanced signal processing techniques, researchers at the Georgia Institute of Technology are peering through layers of pigment to see how painters prepared their canvasses, applied undercoats, and built up layer upon layer of paint to produce their masterpieces.

Devices could be used as flexible connectors for electronics

Devices could be used as flexible connectors for electronics
Researchers at MIT and several other institutions have developed a method for making photonic devices — similar to electronic devices but based on light rather than electricity — that can bend and stretch without damage. The devices could find uses in cables to connect computing devices, or in diagnostic and monitoring systems that could be attached to the skin or implanted in the body, flexing easily with the natural tissue.

Scanning tunnelling microscope for magnetic atoms

Scanning tunnelling microscope for magnetic atoms
Philosophers in ancient Greece already believed that matter is made up of atoms. Only about 35 years ago, however, were atoms actually observed for the first time – in Zurich. The scanning tunnelling microscope developed by Gerd Binnig and Heinrich Rohrer allowed surfaces of materials to be investigated with a spatial resolution of less than one nanometre – enough to see individual atoms.

Optoelectronics works without glass

Optoelectronics works without glass
Researchers at ETH Zurich have developed the first opto-electronic circuit component that works without glass and is instead made of metal. The component, referred to as a modulator, converts electrical data signals into optical signals. It is smaller and faster than current modulators, and much easier and cheaper to make. Optical components for microelectronics must be made of glass.

Hungary’s largest ever projection mapping presentation

Hungary’s largest ever projection mapping presentation
Earlier this year, the 17th FINA World Championships took place in Budapest. The event welcomed nearly 2,500 sportsmen and sports women and 350,000 visitors, making it the biggest sporting event in Hungary’s history. The opening ceremony also saw Hungary’s largest-ever presentation using projection mapping – which was created by Ferenc Varga of Visualpower kft using CAST Software’s wysiwyg lighting design and previsualisation software.
