Propagation delay is not the same, electrical signals travel much slower in semiconductors than light in a vacuum. If you could make an entirely optical chip, size would matter a whole lot less because light will travel much faster through whatever that material will be.
- nyeah 1y agoPropagation delay for light in a semiconductor tends to be roughly equal to propagation delay for electrical signals in a semiconductor. It's not exactly equal because the dielectric constant is a function of frequency. This is assuming you use a waveguide and travelling waves to send the electrical signals. If you charge up the whole line then, sure, that's slower.
