Mechanical Properties and Brittle Behavior of Silica Aerogels
Thierry Woignier,Juan Primera,A. Alaoui,Pascal Etienne,Florence Despestis,Sylvie Calas-Etienne +5 more
TL;DR: Concerning the brittleness features: rupture modulus and toughness, it is shown that pores size plays an important role and Weibull’s theory is used to show the statistical nature of flaw.
Sol-gel channel waveguide on silicon: fast direct imprinting and low cost fabrication
TL;DR: An improved technique based on the sol-gel process enabling to fabricate low loss optical components for integrated optical devices for the lowest cost is presented.

Spectroscopic characterization of intrinsic losses in an organic-inorganic hybrid waveguide synthesized by the sol-gel process
TL;DR: In this article, the authors used 29 Si NMR and near infrared spectroscopy to demonstrate the catalytic effect of zirconium (IV) n -propoxide on the condensation reactions of silanol groups.

Active erbium-doped organic–inorganic waveguide
TL;DR: In this article, a new composition based on hydrophobic sol-gel precursors was developed to reduce the OH quantity, and on a diacrylate monomer whose reactivity allows a high refractive index change under UV light exposure.

Photocurable Sol-Gel Coatings: Channel Waveguides for Use at 1.55 μm
TL;DR: In this paper, the development and characterization of channel waveguides using wet-process, low temperature sol-gel chemistry is described, and two structures have been developed: one is a one-layer structure composed of a mixture of photopolymerizable organosilicate and organozirconate precursors, and the other is a multilayer structure with a buffer under the guide and a protective coating.
