With Fiber Comes Miles-Long and Multiplexed Sensors How do you spot a landslide before it happens, or improve the efficiency of an airplane or rocket engine? Fiber may be the answer. Fiber sensors can transport interrogating light into otherwise...
EDITORIAL
Remembering Teddi Laurin, a Photonics Industry Champion As I began to write this editorial, I was reflecting on 2015 and the technological advancement and innovation we’ve seen industrywide. However, my thoughts quickly turned to our founder, Teddi Laurin, to whom we said goodbye on Nov. 5. She is widely credited with ushering the term “photonics” into popular and global use during her expansive career that began in the early 1960s,...
TECH PULSE
Attosecond Observations Probe Chemical Reactions Laser pulses have been used to track the movements of electrons in molecules with a time resolution of 100 attoseconds — and even to alter their behavior. Demonstrated by researchers at the...
Prisms, Masks Recreate Color Images from White Light Full-color images can be projected using only two gray scale masks printed on transparencies affixed to a prism. A team from Disney Research Zurich demonstrated the effect and presented their...
Driver Creates Short, Powerful Pulses with LEDs Providing high-brightness, rapidly pulsed, multicolor light, a new LED driver could displace more expensive lasers and other light sources in scientific, industrial and commercial uses. Researchers...

Microscopes Expand Operating Room Capabilities Surgeons have long used microscopes to help them perform their delicate work. But, in this setting at least, microscopes have traditionally done little more than magnify. Two new devices aim to...
Metamaterial Offers Simpler Route to Slow Light Manipulating the speed of light more effectively than cold-atom methods, a metamaterial design could find use in optical networks and sensors. The "slow light" effect was demonstrated using terahertz...
VCSELs Enable Deeper Brain Imaging Using light to look more deeply into the living brain could give scientists a better understanding of how dementia, Alzheimer's disease and brain cancer develop over time. Vertical-cavity...
