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?

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

@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.

Bit Error Rate and Test Setup

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

Any more data on these two topics?

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.

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...

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.

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
