This model investigates the wave propagation in a photonic crystal that consists of GaAs pillars placed equidistant from each other. The distance between the pillars determines a relationship between the wave number and the frequency of the light, which prevents light of certain wavelengths propagating inside the crystal structure. In the COMSOL model you refer to they sweep k from 0 to 0.5 because of the way the kx and ky vectors are defined: there is a factor of 2 in the b1x, b1y, b2x, b2y definitions. In our model we don't have that factor so have to sweep over k from 0 to 1. Regarding your first question, yes you need to sweep the other 2 sides as well.Sep 05, 2020 · This study has reported an extremely high sensitive and nonlinear chemical sensor based on photonic crystal fiber is presented with numerical investigation.
