I'm curious if this move by TSMC can use this research?: https://spectrum.ieee.org/microled-optical-chiplet

They seem like related attempts at creating optical processors.

OP's link is about a photonic transistor using graphene. Your link is about making interconnects using individual LEDs and fibers in parallel instead of putting multiple wavelengths on one fiber. They are only superficially related.
