Sol–Gel Processed Lasers and Related Optical Materials

Abstract

The paper presents the method by which transparent glassy materials can be prepared using sol-gel technology which can be based on inorganic materials and a combination of inorganic and organic precursors. During the formation at a stage of liquid phase, a large number of optical materials can be incorporated. The final product may result in a large number of optical materials such as lasers, active waveguides, sensors, and luminescent solar concentrators (LSCs). Surface plasmons originated from silver, gold, and copper nanoparticles can greatly

Mode Sensitivity Exploration of Silica–Titania Waveguide for Refractive Index Sensing Applications

“…Adjusting the set-off precursors and solvents, as well as the stoichiometric ratio between the silica and titania compounds and the thermal treatment temperature, will regulate the refractive index and thickness of the thin films formed by the sol-gel method. These WGs can be doped with rare-earth elements, laser dyes, and other organic compounds, enabling silica and titania materials created by the sol-gel method to be used in optical amplifiers, laser-active media, and sensing applications [10,11]. The sol-gel method is exceedingly effective and does not require expensive high-tech apparatus.…”
