influence of this amplifier on telecommunications
Link title At the time of the work by Elias Snitzer et al, the prospects of optical fibres for telecommunications were not foreseen - since that was not taken seriously until the work of Charles Kao. The subsequent need for and development of amplifiers for optical fibre communications (e.g. mainly the erbium doped amplifier) came some 20 years after Snitzer's work. Thus although work of D. Payne et al and others who did the initial development work on the Erbium-doped amplifier does credit Snitzer (as stated in the Nomination documents), it seems that this may have been a quite minor influence. Therefore, I suggest that the supporting documents for the Snitzer proposal should make this clearer than they seem to at present. E.g. I am suggesting that perhaps the Snitzer amplifier work did not really lead in a direct way to the amplifiers actually used in the telecom domain for optical fibre transmission.

This milestone plaque wording implies that this milestone directly lead to other innovations in the field. It appears from this comment that really the work of Charles Kao more causally lead to those innovations. Perhaps the last sentence of the plaque needs revision then? Confining the plaque to the innovation at hand may be better than attributing the progression of the overall field to a specific sequence of innovations if the chain of precedence is not indisputable. This milestone may stand better recognized on its own.
[responding to Tony Davies] I fully agree that the work of Payne and others was essential to the development of optical fiber amplifiers suitable for optical communications and have made the suggested modifications to the text.

This looks like a good nomination and is certainly of regional and most likely of global significance. I think it will be a good addition to our milestones.
The comments about the rise of fiber communications was not directly based on the AO work illustrate some of the challenges of determining the evolution of inventions and technologies, especially how they are often built on the work of others who were not thinking of those particular evolutions.
A deserved Milestone and the comments clean up the original citation nicely.
I would like to see the acronym AO (American Optical) defined in the nomination and present on the plaque. I think the full name is more important than the physical address mentioned in the citation.
If we delete the "now" in the phrase "now routinely" that gives us another word so that we can spell out "American Optical" while remaining under the word limit. The present tense implies the "now," so that presumably could be deleted without changing the meaning.
This is a worthy nomination. It is also well documented. I tend to agree with the various editorial comments, and do not feel the need to repeat them. I will leave it up to the citation expert to fine tune the wording, but I tend to support the Milestone as meritorious.
