RESUMO:

In this work, the Vectorial Beam Propagation Method (VBPM) is applied in the analysis of quasi-periodic segmented waveguides. The structure has an intercalated refractive index along the propagation direction, following the Fibonacci sequence, which in this case is applied in order to reduce scattering losses caused by imperfections in the walls of the guiding region. The VBPM is expressed in terms of the transverse components of the magnetic field, including Perfectly Matched Layers (PML). Some models of dielectric structures will be studied such as: analysis of the rectangular guide of pure silicon immersed in a substrate of silicon dioxide and analysis of the rectangular guide of pure silicon with substrate of silicon dioxide and upper cladding of SU-8, a photoresist material. The study is based on the analysis of propagating transversal modes, power along the guiding region and the chromatic dispersion at the end of the guide. The computational simulation is obtained using the language FORTRAN 2008 in conjunction with the PYTHON programming language.
