Re: [802.3_100GNGOPTX] Next Generaton 100 Gbs/ PMD technology alternative commentary



Hi Yuri,

There are many perspectives on Si Photonics, which is as expected since we are dealing with a new field.

 

Since you have found assumptions and conclusions

in the Commentary that you disagree with you, you may consider presenting the details of why you disagree rather than simply dismissing them as wrong and naïve.

 

I am also not sure why you are contrasting the Commentary with what “… is being developed in the industry.” Three of the co-authors were or are associated with Luxtera which is shipping Si Photonics based optical cables. One co-author is with IME ASTAR which jointly with LightWire developed novel Si modulator technology. The other two authors have lengthy experience with research and operations in semiconductor processes. I don’t see these authors as just offering an academic viewpoint. On the contrary, they are offering needed caution based on an understanding of the limitations of a nascent industry so that the long term commercial potential is not jeopardized through overpromises.

Chris

It is indeed an interesting article. Just a word of caution - it is written from the academia angle, and, to my opinion, does not really analyze the advantages and disadvantages of silicon photonics as it is being developed in the industry. Some of the conclusions are wrong since they are based on wrong assumptions, and some are just naive. I do not think it can be used for this study group as a basis to assess silicon photonics as a technology  for next gen 100Gb/s.

Dear 802.3 Next Generation 100 Gb/s Optical Ethernet Study Group participants,
 
New technologies have been discussed in the Study Group, with the promise of enabling lower cost and lower power 100 Gb/s PMDs.
 
A recent Commentary in Nature Photonics gives an insightful perspective on one of these new technologies:  Si Photonics. The lead author is Michael Hochberg co-founder of Luxtera and now a Professor at the University of Washington researching Si Photonics. His co-authors are leading researchers and engineers in the field of Si Photonics. The article achieves a good balance between identifying near term limitations and long term promise.
 
Nature Photonics is a by subscription publication. However, the Nature Publishing Group has generously made the Commentary available free of charge to 802.3 NG 100G OE Study Group members to support investigation of 100 Gb/s PMD technology alternatives.

The Commentary will be placed on the below web site for use by 802.3 participants only, in support of Next Generation 100 Gb/s PMD definition efforts.

 
ftp://ftp.finisar.com/
user:      ieee
pwd:     ieee8023
file:       Hochberg_NP_2012.pdf
 
The Commentary is not to be used for any commercial purposes.
 
Since this email references an external ftp site, which is not considered archival grade by 802.3, it will be removed from the 802.3 email reflector archives after a period of time, as per established precedence.
 
Thank you

Chris
