摘要：
This paper presents finite element modeling of an adhesively bonded coupler for the transfer of acoustic modes between two optical fibers. Acoustic modes are propagated through optical fibers for Lamb wave detection with remotely bonded Bragg grating sensors. The model output is compared to previous experimental data, varying the relative diameter of the two fibers. Parameter sweeps of the coupler geometry are also performed to understand how they affect the coupling coefficient.
