“…An important effect on the transmission of signals through optical fibers is the power transfer related to fiber coupling, which is necessary for the most diverse applications. Among the various classes of optical fiber couplers, the couplers based in Photonic Crystal Fiber (PCF) present great research interest due particular spectral features, high performance and great directionality potential applied in high-rate ultra-broadband communication systems [1]- [3]. PCF has revolutionized optical fiber technology due to new degrees of freedom for fiber design, fabrication, and applications which could be achieved.…”

This article presents the theoretical analysis of a signal coupling between a proposed Photonic Crystal Fiber (PCF) and a Conventional Fiber with Step Index (CFSI) system. In this analysis, the Finite Element Method (FEM) and Beam Propagation Method (BPM) are applied together with Daubechies wavelets as basis function and described in the mathematical formulation. The simulations were performed casting the PCF signal into CFSI core using the PCF refractive index. For simulation purposes, the cladding material refractive index was set as 1.5% lower than the core index. The application of Daubechies wavelets as basis functions in BPM analysis presented insertion loss around 3.8% during the fiber coupling.
