Diode, yes, but time reversal?

A micro miniature optical diode that is compatible with semconductor manufacturing processes could indeed open up many exciting new possibilities -- but is it really non-causal? Your headline seems to suggest that the output appears before the input -- or did you mean something else by "time reversal?"

Time, only goes in one direction.

Terminology aside, Time marches ever forward.

Optical wavelengths and electroonic signals all work the same way.  Different materials change the rate at which each wavelength propagates through the substance.  It is not time reversal, it is just index of refraction.

I do agree that the optical frequencies are probably our next venue of exploitation, but the real payoff comes from the X-ray frequencies and above.

Freedom from EMC issues!!

Kudos to the team for the revolutionary discovery!! Don't really understand how it works as I lost touch with optics/quantum physics. I guess, the work is going on to have Optical PCBs and Optical ICs, so I guess life would be easier as the products made out of optical ICs and optical PCBs would be much less prone to EMI/EMC issues? While feeling happy about that, at the same time a thought that occurs...it would be a different world for the engineers...how one would probe signals for debugging? A new set of tools would evolve and may be a new set of standards too to comply with?

Whatever it might be it would be fun... :)

The component devices are still big, but can they each do the work of thousands of transistors?

The vast majority of the embedded designers I know typically create MCU-based systems -- they rarely even consider using a Field-Programmable Gate Array (FPGA).

Like many of you, I was saddened to hear the news of Leonard Nimoy's death. His Star Trek character Mr. Spock was an inspiration to many of us who entered technical fields.
