What Is Optical Computing (Computing At The Speed of Light)

What Is Optical Computing (Computing At The Speed of Light)

This video is the eighth in a multi-part series discussing computing and the first discussing non-classical computing. In this video, we’ll be discussing what optical computing is and the impact it will have on the field of computing.

[0:27-6:03] Starting off we’ll discuss, what optical computing/photonic computing is. More specifically, how this paradigm shift is different from typical classical (electron-based computers) and the benefits it will bring to computational performance and efficiency!

[6:03-10:25] Following that we’ll look at, current optical computing initiatives including: optical co-processors, optical RAM, optoelectronic devices, silicon photonics and more!

    This video has me imagining a hybrid Quantum and Optical computer system.

  2. Geek Gear on October 7, 2019 at 2:50 pm

    Cant wait i had this idea 12yrs ago.

  3. Jeong-hun Sin on October 7, 2019 at 2:50 pm

    Can’t they try to create an optical computer thousand times faster than the current ones, and try to create one that has a similar speed? Isn’t the latter more achievable than the former? Faster speed is good, but the thing I want is less heat. Even if the speed is the same, if a computer or a smart phone generate significant less heat, people will buy it. Damn heat….

  4. Sonic Seven on October 7, 2019 at 2:52 pm

    Oh yeah cuz I’m burning up all 8 cores right now.. oh yeah the demand for this is so high…

  5. CORZER0 on October 7, 2019 at 2:52 pm

    Crazy stuff!

  6. TMeniaco on October 7, 2019 at 2:53 pm

    CANT WAIT for this tec in 2049

  7. Bikini Man on October 7, 2019 at 2:53 pm

    Understand that the public only uses the oldest models with backdoors all over the place so we can be surveilled at all times.

  8. The Mongoose on October 7, 2019 at 2:55 pm

    This is probably how the computers in Star trek would work.

  9. Horacio Tena on October 7, 2019 at 2:57 pm

    Your videos are amazing!

  10. hypnoticatrance on October 7, 2019 at 2:57 pm

    Please, make next video a bit more slow. It is not easy to follow the text or the speaking.

  11. Bobbito Chicon on October 7, 2019 at 2:58 pm

    If our going to use light to transfer Data in compact space.. Then like the Human Body and how it uses Biophotons you dont even need to use fiber , Or classical hardware.

  12. Del Sydebothom on October 7, 2019 at 2:59 pm

    But wouldn’t whatever is generating the photon stream have to be electrically controlled? Why wouldn’t that create a speed bottleneck?

  13. rafik boudjellal on October 7, 2019 at 2:59 pm

    but can it run crysis 3 ?

  14. Fred Cornish on October 7, 2019 at 3:00 pm

    This presentation is like quite a number of others – great info and graphics spoiled by an inhuman velocity. If you must not exceed a specific time, please consider multiple shorter segments allowing the viewer time to absorb the content.

  15. Destiny Fan on October 7, 2019 at 3:02 pm

    Heat is also reduced

  16. Askejm on October 7, 2019 at 3:02 pm

    My grandma paid lots of money to this company that put fiber cables in the ground to her house only for her to buy a 10 Mbit/s internet plan

  17. ♫♪Ludwig van Beethoven♪♫ on October 7, 2019 at 3:02 pm

    Cant believe my child would play on his 10THz PC and i tell him stories about my good old 4Ghz pc 😂

    plus u didn’t mention power requirements and temperature. I’m just assuming, but u could power these babies with led lights which use very little power. Phones as well as pcs would use so little power, your pc will basically run on a small battery. Also no cooling needed coz it’s light, so no more bulky, noisy coolers

  20. rade on October 7, 2019 at 3:05 pm

    Interersting staf , transformed into bullshit , by a background "music". Frequent story on tubbe . MAN WE CANT HERE YOU .

  21. Fergus Moffat on October 7, 2019 at 3:06 pm

    https://www.optalysys.com/news, they’ve just launched there first optical processer 🙂

  22. Rowyn Gaming official on October 7, 2019 at 3:06 pm

    Ghz next up TillaHertz?

  23. science teacher on October 7, 2019 at 3:06 pm

    I have this idea when I was in high school.i am happy to see It’s actually on research state. Good work. Support from india

  25. Dino DiNaso on October 7, 2019 at 3:08 pm

    This presentation moves FAST and is PACKED with good information.

    Normally; tech features are slow with little real content.


  26. Yolo4ever777 King on October 7, 2019 at 3:10 pm

    I have two question about oVPN’s, about using Bell State’s Optical Communications, using oVPN with Superdense_coding is this possible? Would the oscillations device need to have oVPN?

  27. Miguel Pereira on October 7, 2019 at 3:12 pm

    Damn that blond guy was nervous as hell, still gave a solid presentation

  28. nzoomed on October 7, 2019 at 3:13 pm

    I think this could actually be a bigger breakthrough than quantum computing.

  29. GT on October 7, 2019 at 3:13 pm

    i honestly swear i didnt understand a word the guy on the white shirt said about optical computing 😅😅😅

  30. Tim Montgomery on October 7, 2019 at 3:14 pm

    Why you try to make new only in part. Why you conform the language to the old way. 1/0 is no good. Must create new language with new infrastructure to support. An a can be sent as an a. Whole values not separated into bits.

  31. CaptainCosmic on October 7, 2019 at 3:16 pm


  32. Jule Rulez on October 7, 2019 at 3:21 pm

    BS..I might even believe -but when i heard"Quantum computing" thats it for me…Utter crap..

  33. PUBG TIME on October 7, 2019 at 3:25 pm

    But can I play pubg at 5000 fps in 8k with this optical GPU CPU and RAMS

  34. Richard Deese on October 7, 2019 at 3:26 pm

    Thanks! This is a fascinating field, and one that – strangely – doesn’t seem to get much press. I often hear about Moore’s Law for transistors, and various ways to tackle that issue, but I seldom hear optical even mentioned as a possibility! In a world where we expect to be a full Solar System species in the not-to-distant future, it’s vitally important that we *_do_* discuss and consider optical, as it *_will be_* the way we calculate – and communicate – in such a future. Looking forward to more!; Rikki Tikki.

  35. KidRiver on October 7, 2019 at 3:27 pm

    Performance will be capped intentionally and we will see very slow incremental upgrades to this tech just like with traditional computing. Capitalism HOoO!

  36. Detective Conan on October 7, 2019 at 3:28 pm


  37. Filippo Olivetti on October 7, 2019 at 3:28 pm

    This signify also less temperature?
    (nice vid BTW)

  38. meareAaron on October 7, 2019 at 3:30 pm

    optical ram… the next level of RGB

  39. Brian on October 7, 2019 at 3:31 pm

    Great video, but there were a few points where it was hard to understand what you were saying. Just slow it down a bit 🙂

  40. Timothy White on October 7, 2019 at 3:32 pm

    I never knew David Spade was a German scientist.

  41. Fucked Gplus on October 7, 2019 at 3:35 pm

    Ho swell remember cathode tube. And how they used magnet to redirect photons… Jeezz imagine a photon based computer in with anny magnetic field could fuck up everything…. I mean we are talking atom size computing here

  42. Its Me on October 7, 2019 at 3:35 pm

    maybe in the next 30 years this will be useable for comsumers but for now, dont even try to think about it, NO USE.

  43. geoffrey marsters on October 7, 2019 at 3:35 pm

    I have a great idea email me

  44. Lakario Davis on October 7, 2019 at 3:36 pm

    omg what futuristic technology. and well-discribed video. totally understandable!

  45. Omikron on October 7, 2019 at 3:40 pm

    I need this speeds in my brain. Our brain is so slow compared to this compution Power/speed.

  46. san wris on October 7, 2019 at 3:41 pm


  47. Matthew Thomson on October 7, 2019 at 3:43 pm

    wouldn’t optical electronics also mean that little to no heat is produced? meaning that not only is it more energy efficient, servers wouldn’t need expensive mass cooling and also allowing for high-end fanless laptops and desktops. It would change computing as we know.

  48. Shadow Heart on October 7, 2019 at 3:44 pm

    Goddamn those latency numbers. I never even dreamed of latency that low!

  49. Goran B on October 7, 2019 at 3:47 pm

    "Speed of light" and "flow of electrons" (0:40) is very misleadnig, since electric signal is faster than optical signal (due to the permeability) and it has nothing to do with the "flow of electrons"! The faster "speed" is due to bandwidth and not due to speed of electrons/photons.

  50. Suryanshu Sharma on October 7, 2019 at 3:48 pm

    Imagine, how many fps ??
