Stanford engineers use nanophotonics to reshape on-chip computer data transmission

A team at Stanford's School of Engineering has demonstrated an ultrafast nanoscale light emitting diode (LED) that is orders of magnitude lower in power consumption than today's laser-based systems and able to transmit data at 10 billion bits per second. The researchers say it is a major step forward in providing a practical ultrafast, low-power light sources for on-chip computer data transmission.

Stanford's Jelena Vuckovic, an associate professor of electrical engineering and the study's senior author, and first author Gary Shambat, a doctoral candidate in electrical engineering, announced their device in paper to be published November 15 in the journal Nature Communications.

Vuckovic had earlier this year produced a nanoscale laser that was similarly efficient and fast, but that device operated only at temperatures below 150 Kelvin, about 190 degrees below zero Fahrenheit, making them impractical for commercial use. The new device operates at room temperature and could, therefore, represent an important step toward next-generation computer processors.

"Low-power, electrically controlled light sources are vital for next generation optical systems to meet the growing energy demands of the computer industry," said Vuckovic. "This moves us in that direction significantly."

Single-Mode Light

The LED in question is a "single-mode LED," a special type of diode that emits light more or less at a single wavelength, very similar to a laser.

"Traditionally, engineers have thought only lasers can communicate at high data rates and ultralow power," said Shambat. "Our nanophotonic, single-mode LED can perform all the same tasks as lasers, but at much lower power."

Nanophotonics is key to the technology. In the heart of their device, the engineers have inserted little islands of the material indium arsenide, which, when pulsed with electricity, produce light. These islands are surrounded by ph
