Phenomenon used in optical fibres
WebFiber Fuse. Definition: the effect that an optical fiber “burns” from the output end under the influence of an intense laser beam launched into the other end. Category: fiber optics and waveguides. How to cite the article; suggest additional literature. Author: … WebMentioning: 5 - Optoacoustic vibrations in optical fibres have enabled spatially resolved sensing, but the weak electrostrictive force hinders their application. Here, we introduce photothermally induced acoustic vibrations (PTAVs) to realize high-performance fibre-based optoacoustic sensing. Strong acoustic vibrations with a wide range of axial wavenumbers …
