SUMMARY:

This dissertation delved into periodically segmented waveguides, where segmented
guides refer to those with non-trivial geometries where propagation mechanisms are
not obvious. The study explored the behavior of their propagation modes and polarization
through numerical simulations using the 2D Finite Element Method. The
formulation for waveguide mode analysis was employed, enabling the investigation of
the impact of variations in the core geometry (radius, width, gap, and core period)
on their guiding properties for TE and TM modes. The dissertation also examined
the influence of materials (silica, silicon carbide, and silicon nitride) composing the
waveguide on the dispersion relation. This involved analyzing how material properties,
such as refractive index and absorption characteristics, affect the propagation
features of modes within the waveguide
