Abstract

FILTRO INTERFERENCIAL DE BANDA ESTRECHA CON MATERIAL FOTORREFRACTIVO ESTA REALIZADO GRABANDO UNA RED HOLOGRAFICA EN UN MATERIAL FOTORREFRACTIVO, LA CUAL POSTERIORMENTE ES FIJADA CON UN TRATAMIENTO TERMICO. MEDIANTE DOS HACES (13) Y (14), INCIDIENDO EN EL MATERIAL FOTORREFRACTIVO (23), PRODUCEN UNA VARIACION DE LA INTENSIDAD LUMINOSA ESTACIONARIA EN SU INTERIOR. ESTA MODULACION CAMBIA EL INDICE DE REFRACCION POR EFECTO FOTORREFRACTIVO. EFECTUANDO ESTE PROCESO A ALTA TEMPERATURA (180 C), RESULTA UNA FIJACION DE LA MODULACION DE INDICE DE REFRACCION. EL DISPOSITIVO REFLEJA UNA BANDA ESTRECHA DE LONGITUDES DE ONDA REFLEJADOS, CON EL MAXIMO EN DOS VECES EL ESPACIADO DE LAS FRANJAS DE INDICE DE REFRACCION. SE CONSIGUE UNA SINTONIZACION DE LA BANDA FILTRADA USANDO EL EFECTO PIEZOELECTRICO INVERSO DEL MATERIAL.
