There is a great survey article that Larry Coldren published in 2011, which lays out the rationale for longer wavelength VCSELs.
In particular this is Fig. 5 from the article.
The technical authors of
the 1060nm proposal should have included this reference since they are all Larry's students. 😀
It's interesting to speculate how much more the MMF optical interfaces would have been used, especially recently at higher speeds, if we had listened to Larry and adopted 980nm for 802.3 standards, instead of 850nm as advocated by the fiber manufacturers. Hopefully,
this is a reminder to all of us that fiber optical communication is all about the laser, and everything else is in support of it.

I was surprised to learn that a number of participants are not aware of foundational VCSEL work.
The seminal text is the first edition of "Diode Lasers and Photonic Integrated Circuits" by Larry Coldren and Scott Corzine published in 1995. The book has been widely accepted and adopted as a textbook and a key reference book for engineers dealing with semiconductor
lasers and photonic integrated circuits worldwide. The first edition of the book has been translated into Chinese. The second edition of "Diode Lasers and Photonic Integrated Circuits" by Larry Coldren, Scott Corzine, and Milan Mašanović was published in March
of 2012. This new edition was expanded and improved with new material.

“ The book is very clearly written and has many demonstrated examples. It is a valuable resource for anyone who wants to learn about basic optoelectronic devices with every-day applications.” (Optics and Photonics News, 4 January 2013)

Larry Coldren is a VCSEL (and other laser type like tunable) pioneer.
We should periodically remind ourselves that we are standing on the shoulders of giants.
