Abstract
This paper presents the numerical modeling of optical and acoustic wave characterization for a tapered fiber with Finite Element Method. Result focuses on the evolution of surface acoustic wave in the fundamental mode and a higher order acoustic mode behavior of a tapered silica fiber with radius of 2 ?m. Result also presents the difference in overlap integral for various fiber radius at different propagation constants. Also, the co-existence of surface acoustic wave and hybrid acoustic wave are simulated at fiber radius of 6 ?m. A reliable modeling tool is developed to be utilized in Brillouin characterization for various fibers which is applicable in communication, sensor and amplifier. � 2017 IEEE.
