Calculating the coupling efficiency between single-mode fiber to photonic crystal fiber using the FDTD method

摘要

With advances in photonic crystal and photonic band gap research, the interest in interconnecting traditional guided wave devices to the new photonic crystal layout has greatly increased in EMC community. However in order to take complex electromagnetic effects such as radiation, reflection, and coupling into account, full-wave numerical modeling must be considered. This paper investigates the wave coupling performance of a photonic crystal fiber (PCF) and photonic band gap (PBG) structure using the finite-difference time-domain (FDTD) method. We also illustrate the application potential for using the FDTD method for the estimating the coupling efficiency.
