Abstract
PREFORMA A PARTIR DE LA CUAL SE PUEDE ESTIRAR UN FILAMENTO DE GUIA DE ONDA OPTICA CON INDICE EN GRADIENTE. COMPRENDE UNA CAPA DE REVESTIMIENTO EXTERIOR, UNA CAPA DE BARRERA DISPUESTA EN LA SUPERFICIE INTERIOR DE PARED DE LA CAPA DE REVESTIMIENTO Y UN NUCLEO DE VIDRIO DE GRAN PUREZA CON UN INDICE DE REFRACCION EN GRADIENTE, ADHERIDO A LA CAPA DE BARRERA PARA FORMAR UNA ZONA DE TRANSICION , CONTENIENDO DICHO NUCLEO SILICE IMPURIFICADO CON UNA CANTIDAD DE UN OXIDO SUFICIENTE PARA AUMENTAR EL INDICE DE REFRACCION DEL NUCLEO A UN VALOR MAYOR QUE EL DE DICHO REVESTIMIENTO EXTERIOR. EL GRADIENTE DE CONCENTRACION DEL OXIDO DEBE SEGUIR UN GRADIENTE DE LEY EXPONENCIAL ENTRE EL EJE DEL FILAMENTO Y UN RADIO RD MENOR QUE EL RADIO RA DEL NUCLEO, DE TAL MANERA QUE EL INDICE DE REFRACCION ES MAXIMO EN EL EJE DEL FILAMENTO, AUMENTANDO LA CONCENTRACION DEL OXIDO EN LOS RADIOS COMPRENDIDOS ENTRE RA Y RD MAS DE PRISA DE LO QUE AUMENTARIA LA CONCENTRACION DEL OXIDO SI EL GRADIENTE SE PROLONGASE HASTA ENTRAR ENLA REGION COMPRENDIDA ENTRE LOS RADIOS RA Y RD.
