Tiny lasers on silicon A group of scientists from Hong Kong University of Science and Technology, the University of California, Santa Barbara, Sandia National Laboratories, and Harvard University were able to fabricate tiny lasers directly on silicon. To do this, they first had to resolve silicon crystal lattice defects to a point where the cavities were essentially equivalent to those gr... » read more

Do-it-yourself optoelectronics The University of Illinois at Urbana-Champaign has developed a technology to make optical components on a do-it-yourself basis. To make a component, researchers have devised what they call plasmon-assisted etching. The process makes use of a nanostructured template, which can be used to create optical components. The template is a 2D array of gold pillar-su... » read more

Technology Tsunami Approaches


How many times have we heard the saying that technology advancements are accelerating and that inevitably the older generation will have increasing problems keeping up with the new advancements? This happened to me with software development methodologies over fifteen years ago. I still program, when people actually let me, using basically the same techniques I learned when I was in my teens.... » read more

Double Big Mac chips Using molecular beam epitaxy (MBE), Cornell has devised a method of growing an emerging class of oxide films called Ruddlesden-Poppers. These oxides are layered structures, which consist of 2D-based perovskite slabs interleaved with cations. In the future, these structures could be used in various applications, such as superconductivity, magnetoresistance and ferromagne... » read more

Diamond chips The optical transistor, which transports photons, holds great promise. Photons are not only faster than electrons, but they have less crosstalk. But optical transistors are also expensive and difficult to produce. In a possible breakthrough, the ICFO-Institute of Photonic Sciences has demonstrated a “nano-size” diamond that can act as an efficient optical switch. Researche... » read more

Growing tubes Single-wall carbon nanotubes could one day be used in electronics, optoelectronics, biomedical imaging and other applications. But the synthesis of nanotubes with defined chiralities has been a stumbling block. A chiral molecule is a molecule that has a non-superposable mirror image. The University of Southern California has shown that chirality-pure short nanotubes can be use... » read more
