How to design Photonic Crystals Structure Using Lumerical FDTD

Photonic crystal is a periodic crystal structure of dielectric characteristic or showing periodicity in a certain direction. When an electromagnetic(EM)wave propagates in a periodic structure whose period is equal to the wavelength of impulse, then it generates a complete photonic band gap (CPBG). Creation of new defects into the PC structure engenders that particular range of wavelength can be used as propagation region inside the structure. These defects are mainly two types 1. point defect or micro-cavity and 2. line defect or waveguide. 2DPCs consist of dielectric rods in air host (high dielectric pillars implanted in a low dielectric medium) or air holes in a dielectric region (low dielectric rods in a higherdielectric lattice).
