Abstract

UN METODO Y APARATO PARA EXPONER SIMULTANEAMENTE FIBRAS OPTICAS (32), HECHAS DE MATERIAL QUE TIENE UN INDICE REFRACTIVO QUE PUEDE CAMBIAR PERMANENTEMENTE POR LA EXPOSICION A LA LUZ DE UNA INTENSIDAD Y LONGITUD DE ONDA PREDETERMINADA, A DOS HACES DE LUZ DE ESCRITURA (268,272) QUE INTERSECCIONAN E INTERFIEREN EN UNA REGION PREDETERMINADA (30) DE LA FIBRA (32) PARA CREAR UN PATRON DE INTERFERENCIA A LO LARGO DEL EJE LONGITUDINAL DE LA FIBRA (32), DURANTE UN TIEMPO SUFICIENTE PARA FORMAR UNA VARIACION DE INDICE REFRACTIVO PERMANENTE EN LA GUIA DE ONDA. CADA UNO DE DICHOS HACES DE ESCRITURA TIENE UN NUMERO PREDETERMINADO DE LONGITUDES DE ONDA, Y CADA LONGITUD DE ONDA ES SUFICIENTEMENTE DISTINTA DE LA ANTERIOR COMO PARA HACER QUE DICHA VARIACION DE INDICE REFRACTIVO SEA UNA VARIACION APERIODICA. ADEMAS, CADA LONGITUD DE ONDA REPRESENTA UN COMPONENTE FOURIER DE LA VARIACION DE INDICE REFRACTIVO APERIODICO DESEADO.
