Abstract

A square lattice photonic crystal waveguide with dielectric pillars placed in a dielectric substrate with refractive indices 3.4 and 1.45 respectively, is investigated here. An equivalent transmission line model is utilized for wave propagation in the waveguide. Electrical modeling of a defect placed along the planar photonic crystal waveguide is done with an equivalent T section model. Using the scattering parameters for the equivalent T model, spectral characteristics of defects have also been investigated and compared with those obtained by finite domain time difference analysis.
