Overview
Photonic crystal simulation models the propagation and confinement of light in periodic dielectric structures — enabling the design of photonic bandgap devices, waveguides, cavities, and sensors for telecom, sensing, and quantum optics applications. Band structure calculation identifies the photonic bandgap frequency range, while cavity and defect mode analysis computes Q-factor and mode volume — guiding the design of slow-light waveguides and photonic biosensors with high sensitivity.

Key Aspects
Computing the photonic band structure using FDTD or plane-wave expansion methods — identifying the photonic bandgap frequency range and its dependence on lattice geometry and dielectric contrast.
Introducing point and line defects into the perfect lattice to create localised cavity modes or waveguide modes — computing the Q-factor, mode volume, and coupling efficiency.
Analysing the group velocity dispersion near the bandgap edge — designing slow-light waveguides that enhance light-matter interaction for sensing and non-linear optics.
Computing the shift in cavity resonance wavelength per unit change in the analyte refractive index or mechanical deformation — predicting detection limit and sensitivity for photonic biosensors.
