Abstract

METODO PARA LA FABRICACION DE LAS FIBRAS OPTICAS MONOMODO, CAPACES DEACTUAR EN LA GAMA DE LONGITUD DE ONDA DE 1,5 A 1,7 MICRAS, NUCLEOS OPTICOS Y RECUBRIMIETOS OPTICOS DE SILIC%E DOPADA DEPOSITADA DE VAPOR. UNA CAPA DE VIDRIO DE ABSORCION OPTICA DE SILICE DOPADA, QUE INCLUYE OXIDOS DE BORO O DE FOSFORO, ES DEPOSITADA POR REACCION DE VAPOR EN EL ORIFICIO DE UN TUBO SUSTRATO DE SILICE. UNA CAPA DE VIDRIO DE RECUBRIMIENTO OPTICO TRANSPARENTE, DE SILICE DOPADA, QUE INCLUYE GERMANI, Y CON UN INDICE DE REFRACCION MENOR, IGUAL O POCO MAYOR QUEL EL DE LA CAPA DE ABOSORCION, ES DEPOSITADO POR REACCION DE VAPOR SOBRE LA CAPA DE ABOSORCION. UNA CAPA DE VIDRIO DE NUCLEO OPTICO TRASPARENTE DE SILICE DOPADA, QUE INCLUYE GERMANIA, CON INDICE DE REFRACCION MAYOR QUE EL DE LA CAPA DE RECUBRIMIENTO. EN CASA UNA DE ESTAS REACCIONES DE VAPOR SE HA EXCLUIDO EL HIDROGENO Y SUS COMPUESTOS, OCN LO QUE EL ORIFICIO DEL TUBO, DE ESE MODO RECUBIERTO, ES COLAPSADO PARA FORMAR UNA PREFORMA DE FIBRA OPTICA MACIZA. DE ESTA PREFORMA PUEDE OBTENERSE POR ESTIRADO LA FIBRA OPTICA MONOMODO, QUE PUEDEACTUAR COMO PROPAGACION MONOMODAL CON LAS LONGITUDES DE ONDA SELECCIONADAS DENTRO DE LAGAMA EN ESPACIO LIBRE DE 1,5 A 1,7 MICRAS.
