My comment concerned a lack of knowledge of one of the most basic steps in semiconductor fabrication: Lithography (as integral a step in semiconductor fabrication today as it was in the beginning). And not realizing that the light used in lithography has nothing to do with silicon photonics.

"reticles" is a new word in my vocabulary...

"Chip designs come from glass plates known as reticles.
Features on the reticle are transferred to the wafers
using light."
