Calculation of Band Gaps in Photonic Crystals Using FDTD Algorithm

Abstract

Photonic devices can be comprehensively modeled on a computer because Maxvell's equations precisely describe propagation of electromagnetic waves in materials. We use FDTD algorithm to model wave propagation in 2D photonic crystals and to calculate bandgap maps. Programming model was carried out in an environment MATLAB. Their production is based on the following main processes: drawing of the softened glass glassware and waist. The sectional shape of the product and its size are determined by the geometry of the spinneret assembly, drawing speed, and the glass softening temperature.
