Abstract

METODO PARA LA FABRICACION DE FIBRAS OPTICAS MONOMODO, CAPACES DE ACTUAREN LA GAMA LIBRE DE LONDITUDES DE ONDA DE 1,5 A 1,7 MICRAS. UNA CAPA DE VIDRCUBRIMIETOS IO DE RECUBRIMIETO DE SILICE, SIN OXIDO DE BORO Y CON UN INDICE DE REFRACCION NO MAYOR QUE EL DE LA DE SILICE, ES DEPOSITADO POR REACCION DE VAPOR EN EL ORIFICIO DE UN TUBO DE SUSTRATO DE SILICE O EN UNA CAPA DE BARRERA DE LA DIFUSION DE SILICE DOPADA, TENIEDO UN INDICE DE DIFUSION NO MENOR QUE EL DEL VIDRIO DE RECUBRIMIENTO Y NO MAYOR QUE EL DE LA SILICE. UNA CAPA DE VIDRIO DE SILICE DOPADA CON GERMANIA, CON INDICE DE REFRACCION MAS ALTO QUE EL DE LA SILICE, ES DEPOSITADO POR REACCION DE VAPOR SOBRE LACAPA DE VIDRIO DE RECUBRIMIENTO. EN ESTAS REACCIONES SE EXCLUYE EL HIDROGENO Y SUS COMPUESTOS. EL VIDRIO DE RECUBRIMIENTO ES DE SILICE DOPADO CON FLUORINA, SIENDO COLAPSADO EL ORIFICIO DEL TUBO, DE ESTA FORMA RECUBIERTO, PARA FORMAR UNA PREFORMA MACIZA DE FIBRA OPTICA, OBTENIENDO DESDE ELLA Y POR ESTIRADO LA FIBRA OPTICA MONOMODO, LA CUAL PUEDE ACTUAR CON PROPAGACION MONOMODAL CON LAS LONGITUDES DE ONDA SELECCIONADAS DE LA GMA EN ESPACIO LIBRE DE 1,5 A 1,7 MICRAS, EN LA QUE ES PROPAGADA EN DICHO VIDRIO DE RECUBRIMIENTO TODA LA ENERGIA OPTICA ASOCIADA AL CMPO EVANESCENTE DE DICHO MONOMODO.
