Germanium Quantum Wells for High-Performance Modulators in Silicon Photonics
Silicon electronics technology dominates information processing and offers a remarkable way to make very complex systems for very little cost. Many of the waveguide passive optical components used today in telecommunications such as wavelength splitters use the same technology base as silicon electronics — the silicon, silicon dioxide and silicon nitride that are the semiconductors and insulators of electronics become the waveguides of optics. Having one platform that could integrate

In a Disaster, Robots Go Where Humans Cannot
Disaster City, a 52-acre training facility in College Station, Texas, was the setting for a mock-disaster exercise in June. Train wrecks, collapsed buildings and piles of rubble with realistic signatures sprinkled throughout to help rescuers locate...

LCD Panel Market Readjusts
When consumer demand is up for large-size televisions, it would seem logical that profits for all components would be up as well. However, according to the electronics industry market analysis company iSuppli Corp. of El Segundo, Calif., the price...

Monitoring — and Possibly Improving — Superconducting Films
Researchers at Stanford University in California have devised a Fourier transform infrared (FTIR) reflectivity monitoring technique that determines simultaneously the temperature and optical properties of a superconducting film as it is being...

Patterning Films with Fewer Steps
A team of researchers from the University of Illinois at Urbana-Champaign and from Anvik Corp. of Hawthorne, N.Y., has demonstrated a fabrication technique that inscribes patterns onto thin films of indium tin oxide in fewer steps than are typically...

Scanning Light Microscopy Uses Nonlinear Properties of KNbO3 Nanowires
Efficient second harmonic generation and wave mixing make potassium niobate (KNbO3) nanowires ideal sources of tunable, coherent light and instruments for subwavelength microscopy, according to Peidong Yang and his group from the University of...

The Electronic Paper Chase
The growth of flat panel displays over the past decade has been a remarkable story and has enabled the proliferation of flat screens into a number of product categories. Flat panel displays are used primarily in televisions, computer monitors,...

The Making of a Flexible Active-Matrix OLED Display
Imagine a display as thin as paper that can be rolled into a small tube, wrapped around objects such as a cell phone, dropped on the ground or even hammered and yet still function. In addition, the exhibit shows the highly pure color and crisp...

Thin, Colorful Carbon Films
A research group comprising members from Tohoku University in Sendai, Japan, and from Peking University has found that when a thin anodic aluminum oxide (AAO) film on an aluminum substrate is coated uniformly with carbon, the result is an...

Tuning LEDs Is Like Mixing Paints
To get the right light for displays and other devices, you need the proper mix of red, green and blue. Now a team from MIT in Cambridge, Mass., has demonstrated that the same idea can be applied when making LEDs using quantum dots. By using the...

Using Lithography to Enhance LED Efficiency
To increase the brightness of LEDs, the devices’ current-spreading layers can be synthesized from indium tin oxide instead of nickel and gold. Texturing the surface of the indium tin oxide layers can boost light output further. However, techniques...

Adding Depth to Spectroscopy Imaging
Conventional spectrometers examine just one location that scientists hope is representative of a whole sample. With spectroscopic imaging, a single point of information can be replaced by measurements from many locations. Now researchers at the...

Building a Telescope to Supplant Hubble
In 2013, the James Webb Space Telescope is scheduled for launch. Three months later, it will settle into a spot about 1 million miles from Earth, from which it will record light from nearly the beginning of time and from the edge of space. By...

Detecting Motion, No Matter How Small
A virus isn’t big. A few years ago, a nanomechanical sensor found that one tipped the scale at a few attograms. Such instruments now have the potential to sense mass an order of magnitude smaller, on the scale of zeptograms. However, small-scale...

Efficient Semipolar Blue LEDs Created on Freestanding Substrate
Blue LEDs with high quantum efficiency and significantly reduced polarization-related internal electric fields have been successfully fabricated on freestanding semipolar substrates by researchers at the University of California, Santa Barbara....

Electrified Liquid Crystals Make Nanorods Stand Up
Unlike spherical and otherwise-shaped nanostructures, semiconductor nanorods cause light to polarize along their axis. But without the ability to coordinate their orientation, the nanorods’ special capability cannot be fully utilized. Scientists at...

Electron-Multiplying CCD Camera in X-ray Imaging
With the onset of improved, patient-specific treatments for vascular disease, along with advancing diagnostic techniques, there is an increasing need for high-resolution images obtainable in real time. Current state-of-the-art medical x-ray image...

Eye Safety in the Laser Lab
One of the most ubiquitous items on the optical table is the beam block. It gets moved around, sometimes to block a stray reflection, at other times to block a “what if” beam. (What if I miss the mirror?) But despite the beam block’s omnipresence, I...

Glass Molding Makes Aspheric Lenses a Practical Choice
In the early 1970s, Eastman Kodak developed precision glass-molding technology to make 3- to 10-mm-diameter aspheric glass elements for lens systems being designed for cameras that contained film on a disc instead of on a roll. The lens systems had...

Helium-Ion Microscopy
When it comes to imaging at high magnifications, the traditional optical microscope has given way to a number of alternative technologies, each with its advantages and its shortcomings. One, the scanning electron microscope (SEM), has been around...

Infrared Detection at Room Temperature with Single-Electron Resolution
Infrared signals with wavelengths longer than 1.2 μm often are excluded by the selectivity of silicon-based sensors. Sensors that use electron-hole pair generation require photons to have energy greater than the 1.1-eV bandgap energy of...

NIST Develops Calibration Tools for Fluorescent Instruments
Scientists at the National Institute of Standards and Technology (NIST) in Gaithersburg, Md., have developed two new standard reference materials to help correct and validate the performance of analytical instruments that detect, measure and...

Scattering Filter Improves Organic LED
Researchers at MIT in Cambridge, Mass., have created an efficient and saturated deep-blue color by coupling a strong microcavity organic LED with a scattering filter. The technique allowed phosphorescent OLEDs to overcome angular dependence —...

Semiconductor Optical Amplifiers Light Up All-Optical Signal Processing
For many years, optics scientists have been looking for all-optical signal processing materials that enable one light beam to be controlled by another. However, most optical materials are linear and allow light beams to pass through without...
