Advancing the LED revolution

Walk into a typical home improvement store, says Jonathan Wierer, and the progress of the LED revolution quickly becomes apparent.

In the lighting section of most of these stores, says Wierer, an associate professor in the department of electrical and computer engineering and the Center for Photonics and Nanoelectronics (CPN), bulbs made with LED (light-emitting diode) technology account for more than half of the displays.

Energy's future: Nuclear fusion?

Serious discussions of the long-term future of energy use, says Arindam Banerjee, are turning more and more to nuclear fusion, a potential power source that not long ago was considered a distant dream.

Fusion is the process by which the sun generates heat and light. It occurs when two isotopes of hydrogen—deuterium and tritium—collide at great speeds under extreme heat and pressure and fuse to form helium, losing a small amount of mass and releasing huge quantities of energy.

Lehigh-led team develops cross-browser fingerprinting

CSE assistant professor Yinzhi Cao and his group have developed a new way to track web users across browsers.

For good or ill, what users do on the web is tracked. Banks track users as an authentication technique, to offer their customers enhanced security protection. Retailers track customers and potential customers in order to deliver personalized service tailored to their tastes and needs.

A valentine forged from steel

A week from now, most of the nation will be adding their dying roses to the garbage, a sign of another Valentine's Day come and gone.

For the family members and loved ones of students at Lehigh University, however, their "steel roses" will live on for much longer.

Over 100 students from across campus filed into the university's Maker Space at Wilbur Powerhouse in early February to craft a unique Valentine gift and find out more about the various tools and materials the facility has to offer.

Returning to passive radar

Rick Blum and his team are using advanced signal processing techniques to produce models for radar that can be tools for the design of real-world products.

What do you envision when you think of radar? Massive, rotating antennas at airports tracking your last flight? Colorful precipitation maps presented by your local TV meteorologist? Beams sweeping the sky in search of incoming missiles?

A laser-sharp focus

ECE Associate Professor Sushil Kumar has conducted five years of experimental and theoretical research on plasmonic lasers.

Lasers have become indispensable to modern life since they were invented more than fifty years ago. The ability to generate and amplify light waves into a coherent, monochromatic and well-focused beam has yielded applications too numerous to count: laser scanners, laser printers, laser surgery, laser-based data storage, ultrafast data communications via laser light, and the list goes on.
