Aplicación del método de las DFDT a la simulación de dispositivos ópticos

Abstract

[ES] La aplicación de las diferencias finitas en el dominio del tiempo (DFDT) para la simulación de dispositivos ópticos. En el rango de las longitudes de onda ópticas, la aplicación del método de las DFDT ha exigido un elevado coste computacional. La incorporación de distintas formulaciónes ha permitido la aplicación del algoritmo a sistemas ópticos.

[EN] The aim of this work is to apply the difference time domain method for simulating optical devices. The wavelength used in optics makes harder the use of this algorithm in terms of time of processing. In this work different formalisms has been added such as near field to far field transformation, which has permitted to apply this algorithm to simulate optical devices like thin film filters and diffraction gratings. Satisfactory results has been achieved.The irradiance pattern obtained by the FDTD in far field (Fraunhofer region) is compared with analytical curves. Both curves are fit enough, as a result the algorithm has been validated. Rest of applications show the accuracy and potential of this algorithm applied to analyzing optical devices.
