Electrons are so 20th century. In the 21st century, photonic devices, which use light to transport large amounts of information quickly, will enhance or even replace the electronic devices that are ubiquitous in our lives today. But there’s a step needed before optical connections can be integrated into telecommunications systems and computers: researchers need to [..]

The first on-chip metamaterial with a refractive index of 0 gives light an infinite phase velocity, which could be advantageous for manipulating light in photonic integrated circuits. The metamaterial consists of silicon pillar arrays embedded in a polymer matrix and clad in gold film and was developed at Harvard University’s John A. Paulson School of [..]

Interest in molecular imaging has exploded in the last decade, with a solidly established market for pre-clinical small-animal imaging and with steady growth in the demand for human imaging systems to guide surgery and medical intervention. Competition has heated up as the healthcare industry has increasingly recognized the potential of such technologies… Read more

Materials that allow light to pass through without distortion are possible, according to a new set of calculations by an international team of researchers. When a light wave travels through free space, its intensity can be the same everywhere but as soon as it hits an obstacle, the wave is altered. Scattering and diffraction lead [..]

Thanks largely to performance gains and commercial availability, sources based on light-emitting diodes (LEDs) are displacing traditional gas-discharge lamps in fluorescence microscopy systems. Advantages of LED “light engines” include long lifetime, stable output, electronic fine tuning of output intensity, and rapid electronic switching between wavelengths. Read more here

Lasers have a wide range of uses, including as precision heat sources for welding, cutting, marking, forming, peening, hardening, and more recently, 3D printing. Precise energy deposition also makes lasers useful tools for research in high-energy-density science, particularly at very short pulse lengths and high peak intensities. In all of the materials-processing applications, the properties [..]

Today’s consumers aren’t satisfied with products that are static and stationary. Cellphones and tablets have changed the way people think and interact with technology. Composed of a pair of glasses and a frame to hold a cellphone, Wearality is a portable, immersive VR system that provides the deepest immersive VR experience available to consumers. Read [..]

Syntec optics is manufacturing Polymer optics, Plastic injection moulding and biometrics devices and components by the diamond turning process. Diamond turning is an important process to create precision elements through diamond-tipped lathes or various other machine tools. In general, multiple lathes are used which are controlled by computers. However, diamond-tipped lathes are not particularly implemented [..]
