Visualization of the light injection in one dimensional Photonic Crystals.

In this work we present time variation simulations of the light injection in one dimension photonic crystals (1D-PC). This phenomenon is due to the coupling of an incoming plane-wave to the discrete vibration modes in finite 1D-PC. In order to present a live animation of the system we proceed in two stages. First, we present the discrete relation dispersion and then we choose the better combination of frequency and wave-vector. Second, for this combination we reconstruct the field amplitudes in each one of the media. This phenomenon has been described in three previous works [1-3] for the case of a metal-dielectric-metal system. In this work we present the simulation of this system and also the extension of the idea for the case of a multilayer system. The visualization of the electromagnetic field gives a better comprehension of the phenomena. [1]R. Garcia-Llamas, J.A. Gaspar-Armenta, F.Ramos-Mendieta, R.F. Haglund, R.
