Advocate's Review -- Dmichelson (talk) 11:36, 4 January 2020 (UTC)[edit | reply | new]
I've significantly edited the proposal, including the title and citation. I've removed a duplicate set of references and added a significant amount of clarifying text.
The original proposal focused strictly on the events of 1978. There was little mention of subsequent events or the many awards and recognitions that this achievement has received.
The original proposal made frequent mention that this achievement "established an unknown photosensitivity of the fiber." This wording seems a little to me so I've substituted what I believe is more clear.
"In 1978, CRC researchers were the first to observe photosensitivity (photo-induced change of refractive index) in glass optical fibres and demonstrate that the phenomenon can be used to write permanent refractive index gratings that act as very selective in-line optical filters. Fiber Bragg Gratings of this type overcome significant limitations of the prior art and have revolutionized modern optical system design."
The section concerning the obstacles that had to be overcome fails to address the question and should likely be rewritten. However, the rest of the proposals now in good shape.
In my opinion, the case for this proposal is among the strongest that I've yet encountered. I hope that it is approved easily.
Given the number of awards and recognition that this work has received, I don't believe that it is necessary to seek more than one additional expert review.

This is a very deserving candidate. Fiber Bragg Gratings have had tremendous influence on optical fiber communication and this work by Hill et al. was indeed pioneering. I see no reason not to honor it as a milestone in photonics.
