A wide variety of photodetectors are available to suit applications spanning from telecommunications to single-photon counting. Neil Savage takes a look at some of the recent offerings.
Whatever format future quantum information systems take, they are likely to involve single photons in some way. Nature Photonics spoke to Stefan Strauf at the Stevens Institute of Technology about getting the most out of quantum dots.
A growing research and development sector is a sign of a healthy economy. South Africa hopes that a focus on photonics technologies will help drive the country's socio–economic development.
As the size of handheld gadgets decreases, their displays become harder to view. The solution could lie with integrated projectors that can project crisp, large images from mobile devices onto any chosen surface. Duncan Graham-Rowe reports.
A biotechnology boom in India is attracting the interest of manufacturers of imaging equipment who now recognize the country as an important emerging market.
Sophisticated imaging technology will be important for the European Space Agency's Cosmic Vision programme, which aims to answer fundamental questions about the Universe and its origins.
High-performance thermal imaging technology typically involves using cryogenically cooled devices. In the future, detectors based on arrays of tiny optical resonators could lead to sensitive, rapid, thermal imaging at room temperature.
The miniaturization of laser-based atomic magnetometers could be used in neuroscience to investigate the inner workings of the brain. Nature Photonics spoke to John Kitching at the National Institute of Standards and Technology about the latest developments.
The sun is setting on fossil fuels. With the dawn of a new, clean-energy era comes new responsibilities, challenges and opportunities. Those in the photonics community will certainly help to forge the path we take in the coming years.
Photolithography at a wavelength of 193 nm in the deep UV with water immersion lenses can now produce microelectronics containing features with a half-pitch as small as 40 nm. The big question is how much further can the technology be pushed?
