It might very well be a big deal.
This has been done with Indium Phosphide (InP). In fact, lasers, modulators and supporting circuitry have have been integrated together on InP in what is usually referred to as "Photonic Integrated Circuits". Infinera has been doing this for ~20 years. The drawback is you need a very specialized InP fab (which ultimately means high-cost and low volume).
If similar stuff could be done on ordinary silicon, that changes the game and opens up a huge range of possibilities.
- slownews45 5y agoDoes it need to be ordinary silicon, or ordinary silicon processes (including temperature?). One seems much easier than the other, the later seems much more likely to be cheap (I can build a big laser on ordinary silicon today). Much harder to do with ordinary silicon in a somewhat standard process flow.
