We present a very accurate and fast model of Photonic Band-Gap (PBG) structure characterized by a two-dimensional (2D) periodic change of the refractive index and finite height, therefore named quasi 3D PBG. The model is based on the Floquet-Bloch formalism, we have demonstrated to be particularly suitable to design PBG devices. The model allows both a significantly faster convergence than other more complex numerical models, and a greater accuracy than other approximate models. Simulations run very quickly providing the geometrical dimensions, the forbidden frequency range, the propagation constants, the total field distribution and the modal losses.

Abstract
We present a very accurate and fast model of Photonic Band-Gap (PBG) structure characterized by a two-dimensional (2D) periodic change of the refractive index and finite height, therefore named quasi 3D PBG. The model is based on the Floquet-Bloch formalism, we have demonstrated to be particularly suitable to design PBG devices. The model allows both a significantly faster convergence than other more complex numerical models, and a greater accuracy than other approximate models. Simulations run very quickly providing the geometrical dimensions, the forbidden frequency range, the propagation constants, the total field distribution and the modal losses.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
