Behaviour of propagation through one dimension photonic crystal

Abstract

In this work we present a first result of a 1D-photonic crystals (PC) modelling. Our final aim is the characterization of a multimode waveguide which uses this kind of crystal. In this case the optical propagation properties are strongly modified by the anisotropy of the photonic crystal. The transmission of a plane wave depends on the wavelength and its direction. Also the geometries of the structure must be taken into account. The results are obtained by using numerical tools: finite difference time domain (FDTD) and plane wave method (PWM).
