| Popis: | Presented here are the selected optical, physical, and Brillouin-related properties of a novel silica-clad, strontium aluminosilicate (SrAlSi) glass optical fiber produced using the molten core method. The Brillouin gain coefficient was found to be 0.11 × 10−11 m/W, which is about 20 × lower than conventional silica glass optical fibers. The SrAlSi core fiber also has a near-zero temperature coefficient of Brillouin frequency shift (–0.064 MHz/K) and can be considered athermal for all intents and purposes. Additional physical and Brillouin properties of the individual glass components are deduced through the use of an additive model. As a highlight, strontia (SrO) is found to have a large negative Pockels photoelastic coefficient of p12 = – 0.245. Various other bulk properties, such as the acoustic velocity, refractive index, mass density, thermo-optic, and thermo-acoustic, as well as strain-optic and strain-acoustic coefficients are provided. |
