back to article Boffins create bulk-process on-silicon optics

A group of researchers from MIT and the University of Boulder at Colorado say they've moved photonics a step closer to integration with both microprocessors and memory. On-chip photonics offer a number of attractive prospects for chip-makers. Photonic communications generate less heat than electrons moving through copper, and …

And the LASER?

This is a good first move but you still need a source of that light you're going to modulate.

I though they'd have that covered by now with work on light emission from porous Silicon but apparently not.

No

Intel's chip uses the Raman Effect, a process whereby one laser beam - called the 'pump' - is used to amplify a second, low-power, data-carrying beam of a different wavelength. The Raman Effect has predominantly been used to transmit data across very long, multi-kilometre glass fibre optical links, but Intel's goal is to utilise the technique in silicon.

I'm reading "amplification." I'm not reading original emission.

Semiconductor lasers have been COTS for decades. Silicon only semicon lasers, using CMOS standard processes are AFAIK still R&D projects.

But I'll happily be proved wrong.

Intel's chip uses the Ramen Effect, a process whereby one noodly appendage - called the 'pump' - is used to amplify a second, low-power, data-carrying noodle of a different flavour. The Ramen Effect has predominantly been used to transmit data across very long, multi-pint drinking sessions, but Intel's goal is to utilise the technique in meatballs.

There be Pirates ahead!

"create a complete photonic processor and memory system"

Is that the start of the positronic brain ?

I sure hope so.
