Silicon's Achilles Heel is that its indirect bandgap prevents the implementation of high performance integrated lasers which are much desired in photonic integrated circuits.
Damn, finally got some insight into phonons. It would be great if you can write an exclusive article just on Phonons. A term which I keep hearing from Optics people and Physicists, but being in Electronics undergrad, I was never exposed to this.
Nice explanations! It has been a real problem.
Here is a review article on ways to try to put III-V materials together with Si. I think the monolithic trick at end, with trenches, is promising:

Another trenching approach, also reported in 2023 is here:

Looks like trenching will be a thing one way or another, more than one team seems close.
Thanks for the resources! I do want to go into how exactly lasers are implemented in the future.
