Was doing some reading on Intel, thought this was interesting.

"Intel Labs has created the first silicon based optical data connection prototype with integrated lasers, known as the 50Gbps Silicon Photonics Link, advancing the replacement of electronic signals with light beams to carry data.

Currently, at 50 billion bits per second (50Gbps), the link can move data faster than copper technology, and researchers are moving towards even faster speeds and increasing the number of lasers per chip. "

"The transmitter chip is composed of four lasers, with light beams that travel into an optical modulator which encodes data into them at 12.5Gpbs. Both chips are made with low-cost manufacturing techniques similar to those used in the semiconductor industry"

Now if I remember correctly, Dan DeSimone's presentation, he said Poet is capable at 50gbps per color which would be per laser? Correct?

Now it does make a striaght connection to gallium arsenide chips saying they are too expensive, but from my understanding POET is possible to achieve 50gbps per laser. Can someone clairify?
