Heavy light processing

One of the problems with electronics is energy cost. While battery technology has come a long way in recent years, power consumption of electronics is still a major concern. 

Researchers at the University of Colorado have demonstrated a photonics based approach for communication between components at high speed with a low energy burden.

The bandwidth of photonic circuits is higher because different streams of data can be sent in parallel using different frequencies of light – much higher, in fact, than using electrons on wires. Another advantage of using light is that you can more tightly pack the I/O ports on devices, yielding 10 to 50 times the bandwidth density of current technology.

They've demonstrated a hybrid chip that uses state of the art electronics for processing and photonics for I/O using traditional materials and manufacturing techniques. This should make it possible for current manufacturers to quickly adopt and promote this technology. A couple of startups have been spawned that are working on the technology.

Here's a link with more information:
