@measurementBlues: Thank you for making it more clear with the picture you provided. Clearly, as speeds increase, I/O and memory fetch operations move closer to the chip. This could also mean that in the future, entire operating systems can be moved to the memory chip alone.

Re : Photons Coming Down Cloudy Path

The possibilities are endless and this approach to efficient data transfer between modules in a device can probably lower the average power consumption of a processor and its memory modules. If done correctly, this system would allow increased parallel and pipelining performance, thereby reducing processor load, and reducing processor idle time. The only problem remains with laser generators, since devices would get small, laser generators would also have to get small, but without operational compromise.

Remember when faster was free?

Does anyone else see the problems we face in going faster as just more evidience that the future of integration is going to be much much more difficult than anyone predicts? We have had it too easy for too long. More research $ needed when there are fewer and fewer $ available.

Maybe time to finally make the jump to software development from hardware...

I think that some decades of start-ups trying (and failing) to compute with photons showed that at least in the coming decade we will have Electrons for compute, Ions for storage and Photons to communicate

Now we just need to scale optical technology down enough to work efficiently within the chips themselves, with no electronic medium whatsoever! Being able to do all of the signal processing optically, with devices small enough to be printed en masse on a single chip would allow for the highest possible processing speed, would it not?

There are several publications and conference papers of Compss-EOS technology and results (PW, OFC, PS, ECTC etc... - see all at http://compass-eos.com/news-events/events/)

In general we demonstrate BER<1E-12 with MM fibers up to 300m direct optical links between ASIC's, and full reliability tests according to NEBS qualification as described in the Telcordia GR-63-CORE.

It will e interesting to see bit error rate over varied operating environment and long term reliability.

Any more data on these two topics?

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
