Simulation of Optical Coupling between Tapered Fibers and Nanoscale Whispering Gallery Mode Microresonators

Abstract

We investigate use of Lumerical finite-difference, time-domain (FDTD) software for numerical simulation of optical coupling between a tapered optical fiber and a surface nanoscale axial photonic microresonator device with nanoscale radius variation. Simulations utilizing reasonable computational resources (per simulation: approximately 15-h runtime, approximately 10 GB of random access memory) produce spectrograms with good modal structure and demonstrate the feasibility of this approach.
