Putting the Whole Experiment in an Enclosure
Commercial lasers are designed in protective cases that ensure that the beams emerge only from designated apertures, and the typical laser laboratory is protected by interlocked doors and outside warning lights. Between these two levels of laser safety is the enclosure, a box constructed around the laser(s) and all other components on the optical bench. It’s one of the best tools for providing...
New Technologies Power New Eyes
on the Sky
A science that studies exploding stars is itself exploding. Over the next decade, astronomers will more than double the cumulative worldwide telescope mirror area, survey the sky as never before...
The Expanding Role of Lidar at NASA
The growing importance of laser-based remote sensing instruments to NASA scientists and space mission designers is not surprising. Lasers offer clear advantages over passive and active radio-wave...
Is Solar Thermal Power the Answer?
The sun is the source of virtually all of the energy we use. Fossil fuel energy started out as sunlight on plants. In the relative blink of a historical eye, however, we have significantly depleted...
Popcorn-Style Solar Cells
The sun, as the primary source of energy for all organisms on Earth and as a carbon-neutral power source, is considered the ultimate solution to the environmentally friendly energy challenge. In one...
Solar Up, Silicon Down
It is no secret that the growth in solar technologies will greatly affect energy use, but it also is creating a shortage of silicon. Spurring the growth in the solar market are government mandates...
Building a Pocket-Size Electron Accelerator
Might it be possible to combine today’s commercial laser technology with micro- and nanoscale manufacturing techniques to produce tabletop or even pocket-size particle accelerators? This has been the...
Radiation from free electrons
A high-energy electron deflected from a straight-line trajectory emits electromagnetic radiation that is referred to as “synchrotron radiation.” The radiation is highly collimated in the direction of...
Color Quality and Spectra
The primary motivation for development of solid-state lighting is the potential for huge energy savings. The energy efficiency of a light source is measured by luminous efficacy (lumens per watt), a...
Measuring LED Junction Temperature
Manufacturers and solid-state lighting developers are driving LEDs to higher power levels. As more energy is pushed through the LED diode junction, heat removal becomes a critical issue. To assure...
Polarition LEDs Deliver Quantum Efficiency
A new generation of light emitters based on hybrid half-light, half-matter quasiparticles called polaritons promises quantum efficiency and ultralow power consumption. The key feature supporting...
LEDs in the Greenhouse
Plants contain photosensors that respond to parts of the spectrum from the UV to 740 nm and that control various aspects of plant growth. For the past few years, researchers led by John Allen of the...
Building Quantum Dots Slowly
Quantum dots are small, with sizes measured in nanometers. And the size is important because it determines optical properties such as the emission peak of the particle. Bigger quantum dots have...
Determining the Composition of Quantum Dots from Top to Bottom
Quantum dots may shine, but shedding light on their make-up has proved to be difficult because they are small, with sizes in the tens of nanometers. Several analysis techniques average over many...
Confocal Microscopy Enables Direct Observation of Photonic Nanojets
If you shine a beam of light onto a sphere just a few microns in diameter, an unusual effect takes place: On the side opposite where the beam strikes, a local field enhancement shaped like a tiny jet...
Raman Spectroscopy Detects First Signs of Tooth Decay
Dentists commonly use x-rays and metal picks to detect cavities, but Raman spectroscopy could detect tooth decay earlier. With low power and near-IR excitation, it could do so more safely than x-rays...
Vision Sensors Hit the Road
No longer confined to the factory floor, machine vision technology is going for a spin. The same technology that determines whether a label is missing is being pressed into service to manage traffic,...

An LCD Built with Graphene
According to a team of researchers from the UK and Russia, thin sheets of carbon could improve LCDs. The group recently demonstrated that graphene — a two-dimensional layer of carbon — can be used to make the conducting transparent thin films required as electrodes in LCDs and other photonic devices. The insets show two stages of an LCD built using graphene instead of the commonly used...
