What's this about manufacturing photonic reservoir computers with old CMOS processes? We can do matrix multiplication with photon-buckets or what? Edit: I gues

Edit: I guess I'll read the paper for its intro to photonics, I haven't really heard of doing useful math with this stuff https://assets.pubpub.org/xi9h9rps/01581688887859.pdf https://assets.pubpub.org/xi9h9rps/01581688887859.pdf
- mmmBacon 5y agoOptical devices are physically large with waveguides about 1um and and most devices are a few hundred microns in size. The Mach Zehnders that they discuss are 100’s of microns in physical size. So it’s typical that silicon photonics are fabricated in older nodes in part because the resolution of advanced nodes is not needed and it’s a lot cheaper to use the older nodes. Additionally the sweet spot for silicon photonics is a wavelength ~ 1.3um (1.5um) so the node resolution is sufficient for the wavelength used.
