Hyperlens significantly boosts image resolution of microscopic objects

By - May 25, 2015 1 Picture

Using visible light magnified through a compound series of lenses to image small objects, standard optical microscopes have been with us for many centuries. Whilst continually being improved, the result of these many advances of optics and image-capturing techniques means that many high-end optical microscopes have now reached the limit of magnification possible as they push the resolution properties of light itself. In an attempt to resolve this issue, scientists at the University of Buffalo (UB) have created a prototype visible light "hyperlens" that may help image objects once only clearly viewable through electron microscopes.

World's smallest beamsplitter paves way toward computing at the speed of light

By - May 18, 2015 2 Pictures

Silicon photonics is an emerging technology that incorporates electronic circuits using photons of laser light rather than electrons to transmit, receive, and manipulate information. As such, a silicon photonic CPU could potentially process information at the speed of light – millions of times faster than computers available today. In a step towards this goal, engineers working at the University of Utah have developed an ultra-compact photonic beam-splitter so small that millions of these devices could fit on a single silicon chip.

Optical antenna may allow LEDs to replace lasers in host of devices

By - February 4, 2015 3 Pictures
By applying 120 year old radio frequency antenna theory to the much newer field of photonics, researchers at Lawrence Berkeley National Laboratory claim to have produced a prototype optical antenna that increases the intensity of emission from a nanorod light source by more than 115 times. This technique may offer the opportunity to replace power-hungry lasers in short-range optical communications devices with enhanced low-power LEDs. Read More

Researchers achieve long-distance light to matter quantum teleportation

By - September 22, 2014 1 Picture
A successful test in passing information from light into matter – using the teleportation of the quantum state of a photon via optical fiber cable to a receiving crystal located over 25 km (15 mi) away – has been claimed by physicists at the University of Geneva. This test shattered the same team’s previous record and may herald the development of greater, long-distance teleportation techniques and qubit communications and computing capabilities. Read More

Nature inspires color-sensitive, CMOS-compatible photodetector

By - August 28, 2014 2 Pictures
Researchers at Rice University's Laboratory for Nanophotonics (LANP) have developed a new image sensor that mimics the way we see color by integrating light amplifiers and color filters directly onto the pixels. The new design enables smaller, less complex, and more organic designs for CMOS (complementary metal-oxide semiconductor) sensors and other photodetectors used in cameras. Read More

Next-gen smartphones could have sensors built into display glass

By - June 20, 2014 2 Pictures
Gorilla Glass could be getting a lot more useful. Corning International, which makes the material commonly used in mobile device screens, has teamed up with researchers at Polytechnique Montreal to create a new type of glass that incorporates transparent sensors. Soon, the glass in your smartphone screen could be used to take your temperature, among many other possibilities. Read More

Hybrid energy system mimics processes in photosynthesis

By - May 30, 2014 1 Picture
Artificially replicating the biological process of photosynthesis is a goal being sought on many fronts, and it promises to one day improve light-to-energy efficiencies of solar collection well beyond what's possible with photovoltaic cells. One of the first steps is to imitate the mechanisms at work in the transfer of energy from reception through to output. To this end, Scientists have recently experimented with a combination of biological and photonic quantum mechanical states to form new half-light half-matter particle, called the “polariton.” It could help realize fully synthetic systems by mimicking the energy transport systems of biological photosynthesis.
