This seems very huge, or am I missing something fundamental that's not included in the paper?

- misja111 1y agoYes, the fact that contrary to what the title claims, at this point there is no transistor working at petaherz frequency at all. All there is, is a promising new technology.
- amelius 1y agoMaybe they should have mentioned that interconnect on a chip cannot handle these speeds.
- dgfl 1y agoThis is a laser controlled device. Even the terminology of "interconnect" is not really applicable. Your best hope is an optical waveguide coupled to the device, definitely not a metal line. It's not even a transistor in the traditional sense really.
- parsimo2010 1y agoThis has limited applications. It doesn't have a viable path to being used in a CPU or GPU. So we're not going to see a zillion-fold increase in compute speeds from this. Maybe some physicists find it useful for an experiment, but the average joe won't notice anything different about the world.
- kelseydh 1y agoI'm curious if this move by TSMC can use this research?: https://spectrum.ieee.org/microled-optical-chiplet https://spectrum.ieee.org/microled-optical-chiplet They seem like related attempts at creating optical processors.
- parsimo2010 1y agoOP's link is about a photonic transistor using graphene. Your link is about making interconnects using individual LEDs and fibers in parallel instead of putting multiple wavelengths on one fiber. They are only superficially related.
- manmal 1y agoI thought that the speed of light limits the max possible frequency to the sub THz range, at current chip sizes.
