Since you can carry 100+ frequencies around 1500 nm, the feature-size per data stream is more like 15 nm/stream, which is closer to electronics, and the heat dissipation of optical waveguides may be much lower than with equivalent electronics. Photonics also have the advantage of better signal propagation over longer distances, for efficient interconnection of multiple devices.
So there is a likely opportunity for large-scale integrated photonics, as long as you have enough parallelism.

- musicale 3y agoOptics/photonics can potentially perform analog as well as digital computation. One trendy thing at the moment is accelerators for neural networks. Some potential benefits of optics include high data rate, parallel processing of multiple streams, transmission over longer distances, and lower heat dissipation.
