FEATURES
Silicon photonics could save the computer industry The future of computing may need a light touch – literally. As chips move more and more data around, the metallic wiring on and between them eventually won’t be able to keep up. The solution may be silicon photonics, a technology that employs silicon as an optical material. If compatible with standard CMOS semiconductor processing, silicon photonics promises inexpensive optical devices, easy...
MOCVD Systems Meet LED Demand Explosive growth in the backlighting market for televisions, displays, handheld devices and more is creating a ripple effect throughout the LED industry. LEDs are sought after for backlighting...
Planar Lightwave Circuits Enable Next-Generation 40G/100G Networks Many new systems rely on advanced modulation formats such as differential phase shift keying and differential quadrature phase shift keying to complement traditional architectures such as dense...
The Year in Stimulus Funding: The impact of the American Recovery and Reinvestment Act on biomedical research Dr. Francis S. Collins had, as they say, his work cut out for him. In early August 2009, the former head of the Human Genome Project was sworn in as the 16th director of the NIH and thus was charged...
Specialized “shutters” capture superquick phenomena Remember when “faster than a speeding bullet” was exciting news? At about 2700 mph, the quickest ammo is moving turtle-slow when compared with the rates needed to study physical phenomena at the...

TECH PULSE
Laser pulses reveal contact mechanics The next time you are sitting at your desk full of papers, pens, files and perhaps a coffee mug, take a closer look at the points where these objects meet the desk. What do you see? If you could magnify the nanoscale interface of where the object meets the desk, you would actually see a world of mountain ridges and deep valleys.

Sensing the rain The Tropical Rainfall Measuring Mission (TRMM) is a project run jointly by NASA and the Japan Aerospace Exploration Agency to monitor and study tropical rainfall. When tropical cyclone Laurence hit Australia in December 2009, TRMM determined that total rainfall exceeded 150 mm. The three primary instruments onboard the satellite are precipitation radar, a microwave imager, and a visible and...

OCT provides new tool for art historians Scientists in Poland have described how optical coherence tomography (OCT) – a technique most often used in medical imaging – can be used to reveal the forgery of an artist’s signature or changes in inscriptions on 100-year-old paintings. Shown is “Saint Leonard of Porto Maurizio,” an 84 x 121-cm oil-on-canvas picture that hangs in the Franciscan Church of St. Bonaventure in Pako, Poland. Circles...
VIEWPOINT
My Summer with MIRTHE I have never been particularly interested in the field of engineering. Physics? No thank you, I’ll stick to English and history. So when my father came to me with the opportunity to work in a lab in Princeton for the summer, I was feeling more than a little apprehensive. But curiosity (and a desire to work somewhere that paid above minimum wage) got the better of me, and I signed up to be...
EDUCATION WAVEFRONT
From the Industrial Age to the Nano Age Neal C. Gallagher was enjoying being a parent. Retired, the one-time engineering professor wanted to get more involved with his two young children’s schooling. He approached his son’s first-grade teacher about instructing students in the gifted program about science and engineering, and she welcomed the idea.
