Abstract: In this paper, we model the cross-sectional area for transition region of a tapered standard silica fiber using Finite Element Method (FEM). Simulation result shows changes of acoustic wave behavior propagating through the transition region. Frequency shift of transition region for 2 pm to 8 pm core diameter falls between 7.029 GHz and 6.889 GHz. Acoustic velocity for the fundamental mode propagation is calculated to be between 3764.171 m/s and 3687.493 m/s. Based on the results, variation in acoustic wave propagation across taper transition is being analyzed. Also, we study the relationship between fundamental mode acoustic velocity and normalized frequency. © 2016 IEEE.
