Great find blues, here's a quote from your link,
To create a silicon-compatible laser, the scientists needed to produce a form of silicon that can emit light. Researchers from Eindhoven University of Technology (TU/e), together with researchers from the universities of Jena, Linz and Munich, combined silicon and germanium in a hexagonal structure that is able to emit light, a breakthrough after 50 years of work
Oh my! After 50 years they have some breakthrough research! Now let's see if in the next 10-20 years they can turn that into a commercially viable product
Jeeeez
