Abstract
The simulated annealing and effective index methods are used to synthesize a photonic crystal slab line-defect waveguide with its line-defect mode at a minimal group velocity or a fixed group velocity. The simulated annealing is a probabilistic iterative algorithm for finding a global extremum in a nonlinear optimization problem. In this thesis, the conventional plane wave expansion method is used to calculate the band diagram at each step of the simulated annealing process. The effective index method is an approximation algorithm for reducing the three-dimensional slab waveguide problem to an approximate two-dimensional one. The conventional and revised plane wave expansion methods are used together with the effective index method to calculate the final band diagram. The numerical results show that the simulated annealing and effective index methods can effectively be used to synthesize a photonic crystal slab line-defect waveguide with its line-defect mode at a minimal group velocity or a fixed group velocity.
