This paper investigates the formation of resonant modes, within a two-dimensional silicon-based waveguide, intricately perforated with circular and square-type defects using the finite-difference time-domain method. The study systematically examines how the geometry of these perforations - specifically circles with a radius of 360 nm and squares of equivalent side length - influences the emergence and behavior of these modes. A particular focus is given to the influence of the defect shape on the modes, examining configurations where defects are circular, square, or absent (non-perforated segment acting as a defect).
