Plasmonic Waveguide Makes Silicon Shine

Electrically pumped light emitter could be compatible with CMOS

2 min read

27 January 2010—A new method for producing light in silicon could lead to densely integrated optical sensors .

"It could be a new angle to solve this ongoing problem of getting light out of silicon," says Jurriaan Schmitz, a professor of electrical engineering and head of the semiconductor components research group at the University of Twente, in the Netherlands. "We might have a good one in our hands here."

Even as the initial sales receipts for the first transistors to hit the market were being tallied up in 1948, the next generation of transistors had already been invented (see “The First Transistor and How it Worked.”) Since then, engineers have reinvented the transistor over and over again, raiding condensed-matter physics for anything that might offer even the possibility of turning a small signal into a larger one.
