Abstract
PRESENTAMOS UN FILTRO DE BANDA OPTICO POR HAZ DE FIBRAS, EN EL QUE UNA FIBRA DE VIDRIO (1), CUYO NUCLEO ES CONDUCTOR DE LA LUZ, ESTA ENCADENADA CON UNA SECCION POR LO MENOS DE UNA FIBRA DE DOBLE NUCLEO (3). LOS INDICES DE REFRACCION DE LOS DOS NUCLEOS (4, 5; 14, 15; 14'', 15'') DE LA SECCION DE LA FIBRA DE DOBLE NUCLEO (3, 10, 11) ESTAN DETERMINADOS DE TAL MODO QUE SON IGUALES EN LA LONGITUD DE ONDA DE TRANSMISION, Y DIFERENTES EN LOS DEMAS CASOS. LA LONGITUD (I) DE LA SECCION DE LA FIBRA DE DOBLE NUCLEO ES IGUAL A: M I1/2, DONDE I1/2 ES LA LONGITUD EN LA QUE UNA ONDA DE LUZ CON LA LONGITUD DE ONDA LAMBDA 1 SE ACOPLA COMPLETAMENTE, UNA VEZ, DESDE UN NUCLEO (4) AL OTRO (5), Y M ES UN NUMERO IMPAR (M= 1,3...). LOS DOS NUCLEOS, UNO A CADA LADO DE UNA SECCION DE LA FIBRA DE DOBLE NUCLEO, CONECTAN DIRECTAMENTE CON UN NUCLEO (2, 7), BIEN DE LA FIBRA DE VIDRIO (1, 6) BIEN DE LA SECCION DE LA FIBRA DE DOBLE NUCLEO (15'').
