Abstract
Método de diseño de redes de difracción en fibra óptica por variación del periodo de la red para su aplicación como filtro óptico. Método de diseño de redes de difracción de Bragg en fibra para su aplicación al filtrado en el dominio óptico basado en la variación del periodo de la red de difracción a lo largo del eje de la fibra, de acuerdo con la función de apodizado, para mantener constante la condición de Bragg a lo largo de la estructura. Estas redes así diseñadas presentan una mejora de las características del filtro tanto en amplitud como en fase. Respecto de la primera, la característica espectral se aproxima al filtro rectangular ideal, presentando una alta reducción de los lóbulos secundarios que producen diafonía entre canales en los sistemas de comunicaciones ópticas con multiplexación en longitud de onda. En cuanto a la característica de fase, ésta prácticamente consigue un retardo constante ideal y elimina los posibles efectos debidos a la dispersión.Design method of fiber optic diffraction networks by varying the period of the network for application as an optical filter. Design method of fiber Bragg diffraction networks for application to filtering in the optical domain based on the variation of the period of the diffraction network along the fiber axis, according to the apodization function, to maintain constant Bragg's condition throughout the structure. These networks thus designed present an improvement of the filter characteristics both in amplitude and in phase. Regarding the first, the spectral characteristic is close to the ideal rectangular filter, presenting a high reduction of the secondary lobes that produce cross-channel crosstalk in optical communication systems with wavelength multiplexing. As for the phase characteristic, it practically achieves an ideal constant delay and eliminates the possible effects due to dispersion.
