Re: [Jchat] Optical computers
If you'd be interested in patent statistics, this could be of interest to you: https://worldwide.espacenet.com/patent/search?f=oprid%3Ain%3D20020101-20221231&q=cl%20%3D%20%22G06E%22%20OR%20cl%20%3D%20%22G06N3%2F067%22%20OR%20nftxt%20%3D%20%22optical%20computing%22 The query searches CPC Classes G06E and G06N3/067 (corresponding to optical computing and neural networks implemented using optics) and "optical computing". I filtered for applications with a priority date in the last 20 years. The filters also let you make nice graphs of applicants (i.e. companies filing the patent applications), countries, dates, etc. You can also download the results if you'd like. Have fun!

Re: [Jchat] Optical computers
When you look at the switching capacity of high speed optic fiber networks, it's apparent that the switching speed isn't really the obstacle here (Except perhaps in the sense of finding sufficient useful content to feed into it.) -- Raul On Thu, May 19, 2022 at 8:39 PM Björn Helgason wrote: > > https://www.tomshardware.com/news/goodbye-transistor-new-optical-switches-offer-up-to-1000x-better-performance#:~:text='Optical%20Accelerators'%20ditch%20electricity%2C,light%20as%20an%20exchange%20medium.&text=A%20collaboration%20between%20IBM%20and,up%20to%201%2C000%20times%20faster > . > > I remember a proposal of matrix operations that would never stop and never > fail instead they could report eventual failings in items in the resulting > matrix. > > It was in the same conference in copenhagen 1990. > > It would work well with the optical computer. > > On Wed, May 18, 2022, 14:28 Robert Bernecky > wrote: > > > Hi, Björn, > > > > The IEEE does a fairly decent job of keeping me informed > > about progress on the optical (and quantum) computing front. > > IEEE Spectrum, their monthly "flagship" publication is worth > > looking at, either online or at a decent technical library: > > > > https://spectrum.ieee.org/tag/optical-computing > > > > Can you give us some links and/or citations for your reading > > in this area? > > > > Thanks, > > Bob > > > > > > On 2022-05-18 10:00, Björn Helgason wrote: > > > One of the apl conferences I think it was 1989 in copenhagen there was a > > > presentation about optical computers. > > > > > > Have not heard much about it since but it looks like it is coming to the > > > surface again. > > > > > > As far as I remember the presenter said it would fit apl very well. > > > > > > Incidentally Ken Iverson gave me a copy of J on this same conference on a > > > discette. > > > -- > > > For information about J forums see http://www.jsoftware.com/forums.htm > > > > -- > > Robert Bernecky > > Snake Island Research Inc > > 18 Fifth Street > > Ward's Island > > Toronto, Ontario M5J 2B9 > > > > berne...@snakeisland.com > > tel: +1 416 203 0854 > > text/cell: +1 416 996 4286 > > > > > > -- > > For information about J forums see http://www.jsoftware.com/forums.htm > > > -- > For information about J forums see http://www.jsoftware.com/forums.htm -- For information about J forums see http://www.jsoftware.com/forums.htm

I remember a proposal of matrix operations that would never stop and never fail instead they could report eventual failings in items in the resulting matrix. It was in the same conference in copenhagen 1990. It would work well with the optical computer.

Re: [Jchat] Optical
It's odd, but most of the news on that front is about "quantum computing". I can find people working on the optical stuff. For example https://www.academia.edu/34364046/Photonic_integration_on_the_hybrid_silicon_evanescent_device_platform But I guess the news is kind of quirky. I also don't know how I could pursue this kind of thing on a hobbyist scale. -- Raul On Wed, May 18, 2022 at 10:01 AM Björn Helgason wrote: > > One of the apl conferences I think it was 1989 in copenhagen there was a > presentation about optical computers. > > Have not heard much about it since but it looks like it is coming to the > surface again. > > As far as I remember the presenter said it would fit apl very well. > > Incidentally Ken Iverson gave me a copy of J on this same conference on a > discette. > -- > For information about J forums see http://www.jsoftware.com/forums.htm -- For information about J forums see http://www.jsoftware.com/forums.htm
[Jchat] Optical computers
Hi, Björn, The IEEE does a fairly decent job of keeping me informed about progress on the optical (and quantum) computing front. IEEE Spectrum, their monthly "flagship" publication is worth looking at, either online or at a decent technical library: https://spectrum.ieee.org/tag/optical-computing Can you give us some links and/or citations for your reading in this area?

[Jchat] Optical
One of the apl conferences I think it was 1989 in copenhagen there was a presentation about optical computers. Have not heard much about it since but it looks like it is coming to the surface again. As far as I remember the presenter said it would fit apl very well. Incidentally Ken Iverson gave me a copy of J on this same conference on a discette. -- For information about J forums see http://www.jsoftware.com/forums.htm
