EDFA's have been used heavily for the last 15 years. Sure this is a "on a chip" but not quite the revelation the title suggests.
quote:The advantage this scheme offers over previous methods of light amplification is that it works over a fairly broad range of wavelengths.
EDFA's already work very well amplifying the 40 standard DWDM Lambdas. The questions is can these new devices offer the same gain with lower distortions, or higher gain with the same amount of distortion.
quote:The process also creates a duplicate signal at a different wavelength, so the devices could be used to convert a signal from one wavelength to another.
Now that is handy, route and loseless split redundancy!

Three atoms wide... replacing a traditional electrical grid? This is huge, on a chip or otherwise. RFI/etc will be nil, and that's just one of the minor advantages.
