fiberhound What am I to make of all these very impressive academic papers? Do you think they prove anything? I can probably find an academic paper that will prove almost anything is possible and will change the world. Oh, and by the way look at the following quote from your article in post #1744: Cocondensed and copolymerized materials show low optical losses of 0.12 dB/cm at 1300 nm and 0.33 dB/cm at 1550 nm. It has two key points. The loss at 1300 nm is about a factor of three less than at 1550 nm. This is what I reported in my previous post that was one of the problems with Sol Gel. This shows that O-H and C-H are still present. 1550 nm is the wavelength of light used for telecommunications. Another point is that at 1550 nm the loss in Sol Gel is .33dB. This is too high. The glasses used in optical chips made by PIRI, NEL, and Lucent all have losses of less than .05 dB/cm. Lumenon needs to get the loss of Sol Gel down to this level to make competitive DWDM devices (at 1550 not 1300). I hope Lumenon did not reference you to this article since it only proves what I said. You found this on your own, right? Greeze
