Silicon Photonics – Are We Past the Hype?
Both Intel and Luxtera have been working on silicon/CMOS photonics for more than 13 years. While we have a few products, its promise of lower-cost, lower-power-consumption optical devices that would revolutionize the industry has yet to come to fruition.
Let’s look at some of the progress that has been made.Silicon/CMOS photonics has several different implementations. Shown below is Intel’s, which is a hybrid in that it uses InP lasers to produce the light and silicon waveguides to direct it.
