Thanks for the detailed analysis. I'll pass it along to the researchers.

This beam x-y is dependent very much on frequency. All frequencies quoted are dangerous to transistors that can take over them. ~644 nm frequency especially.

There are no 99.9% of fibers compatible. They seem to be inside the chip in the sea of SiO2 ?. 

What is the potential application ?. Does not look like photonic replacement of wires between transistors. For frequency reason.  All these are just another publication of things which were already shown. Photonic crystal laser is well known. A substance is different but does not make useful more than older papers. Best Jan

The researhers say this is only their first non-optimized prototype just proving the concept. Of course, since you are an expert in CMOS fabrication, I respect your opinion and thank you for sharing. For whom do you work?

Does anyone else see a problem with bonding a monolayer of molybdenum ditelluride to silicon as demonstrated by the researchers?

these frequencies will wreak havoc on CMOS transistors in close to them.

1) Very large 2) CMOS has transistors, wires, and non-active elements. Set of substances is very strict. This is different. From my application' point of view no use of it. We do wafer test mixed contact and non-contact. Best to them but no real industrial value.
