8 thoughts on “Photonic Computing”

  1. So, instead of positronic brains our humaniform robots will have photonic brains? If I could be young again, I’d be yearning for my wonderful robot lover. As it happens, I’m writing a book about a guy who falls in love with an alien sexbot (that is, a sexbot designed by aliens for their own use…).

  2. I could swear I saw a very similar story about 20 years ago… so my guess is no, we’re not doing photonic computing any time soon.

      1. “The Lonely,” which I saw as a kid, is the original trigger of the many “robot lover” stories I published between 1990 and 2010. Also, in my 1976 novel “A Plague of All Cowards” there is a robot sidekick who “dies” (blown to bits) for the hero. Both are on the cover, with the robot in the foreground.

    1. The same applies to the current AI being on the track to replace humans.

      And get off my lawn!

  3. What’s interesting about this story is the claim that:

    Second, the technology is compatible with complementary metal-oxide-semiconductor, meaning it can be integrated into existing semiconductor manufacturing processes. “This is seamless and compact,” Chen said. “For the others, it’s very different and complicated physics systems. This one is semiconductor, and it can always be fabricated on chip.”

    This is *distinctively* different than other photonic discoveries I’ve read about. If so, on the scale of technological sophistication, I’d compare this to the development of discrete transistor tech in the mid to late 50s.

    However, that said, it took another decade before SSI (small scale integration) semiconductor chips started showing up in the common DIP configurations that powered much of the semiconductor revolution in the late 60s and early 70s.

    There will be much work to do to characterize these processes as they are scaled up. Let alone characterize signal path delays and behavior at various voltages, currents and temperatures. IF this does become a new base technology we’d be looking at probably a minimum of a decade before it starts to show up in consumer gear.

    One off supercomputers, funded by the government, maybe 5 years out if there were a crash program. Otherwise at least on the same time scale, maybe longer… There is some hysteresis in the HPC world to make current investments pay off before leaping onto the next “great thing”.

    1. If I were *truly* a sarcastic SOB, I’d say you won’t see much of anything of this tech, until the co-discoverers have a major falling out between them and then start up competing companies…
