Optical Fiber Coupler Analysis Using Daubechies Wavelets





Daubechies Wavelets, PCF, CFSI.


This paper presents the theoretical analysis of a signal coupling between a Photonic Crystal Fiber (PCF) and a Conventional Fiber with Step Index (CFSI).  In this analysis, the Finite Element Method (FEM) and Beam Propagation Method (BPM) are applied in conjunction with Daubechies Wavelets used as basis function and introduced in the mathematical formulation. In the simulation, the PCF signal power was launched into the core of the CFSI with a relative refractive index equal to the PCF, considering the clad refractive index 1.5 % lower than the core index.
