Writing with Light: An ‘Etch A Sketch’ Electrical Circuit

Physicists from Washington State University (WSU) have used lasers to draw conductive circuits into a crystal. The achievement demonstrates a new kind of transparent, three-dimensional electronics: circuits that can be erased and reconfigured, like the drawings of an Etch A Sketch.

Asphere Measurement System

The AspheroCheck UP from TRIOPTICS (Weden, Germany) is designed with a completely automated measurement process that requires no manual interaction to accurately measure aspheres. Lenses with aspherical surfaces are frequently used in small, light, high-performance optics to reduce spherical aberration. While the decentration of an aspherical surface can be determined with the centration measurement that is also used for spherical lenses, determining a possible tilt requires an additional, off-axial test.

World’s Brightest Laser Sparks New Behavior in Light

Physicists from the University of Nebraska-Lincoln are seeing an everyday phenomenon in a new light. By focusing laser light to a brightness 1 billion times greater than the surface of the sun — the brightest light ever produced on Earth — the physicists have observed changes in a vision-enabling interaction between light and matter. Those changes yielded unique X-ray pulses with the potential to generate extremely high-resolution imagery useful for medical, engineering, scientific and security purposes.

New Class of ‘Soft’ Semiconductors Could Transform HD Displays

A new type of semiconductor may be coming to a high-definition display near you. Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that a class of semiconductor called halide perovskites can emit multiple, bright colors from a single nanowire at resolutions as small as 500 nanometers. The findings represent a clear challenge to quantum dot displays that rely upon traditional semiconductor nanocrystals to emit light. It could also influence the development of new applications in optoelectronics, photovoltaics, nanoscopic lasers, and ultrasensitive photodetectors, among others.

'Magic' Alloy Could Spur Next Generation of Solar Cells

In what could be a major step forward for a new generation of solar cells called "concentrator photovoltaics," University of Michigan researchers have developed a new semiconductor alloy that can capture the near-infrared light located on the leading edge of the visible light spectrum. Easier to manufacture and at least 25 percent less costly than previous formulations, it's believed to be the world's most cost-effective material that can capture near-infrared light—and is compatible with the gallium arsenide semiconductors often used in concentrator photovoltaics.

Microstructural Explorations Inside Fuel Cells

Solid oxide fuel cells (SOFCs), a promising technology that can efficiently produce energy using fossil fuels with no moving parts and low emissions, present a particularly perplexing economic challenge: current systems operate at maximum efficiency between 700 and 1000 degrees Celsius, but such high temperatures shorten their service life, requiring more frequent fuel cell stack replacements. Lowering the operating temperature makes them last longer, but requires additional cells in the stack to deliver the same performance, and that drives up costs.

CMOS The Future of Image Sensor Technology

CMOS imaging is trending to become the dominant imaging technology. Initially, CMOS was limited by its inherent noise. Architectures were then essentially analog and the idea of integrating the image processing features with System On Chip (SoC) technology was yet to be considered. However, it is fundamentally this SoC characteristic of CMOS that has driven impressive growth. Over the years, this technology has become more and more competitive. The commercial race started in early 2000 when the big players applied continuous improvements to electro-optical performance.
