Abstract
ESTRUCTURA DE FIBRA OPTICA UTILIZADA CON SEÑALES OPTICAS AMPLIFICABLES, FORMADA POR UNA LONGITUD DE FIBRA OPTICA (1) QUE INCLUYE DOS NUCLEOS OPTICOS (2,4) DE MODO UNICO SEPARADOS UNIFORMEMENTE, SITUADOS JUNTO CON UNA CAPA (6) DE MANERA QUE SE FORMAN DOS TRAYECTORIAS OPTICAS. LAS CARACTERISTICAS OPTICAS DE LOS NUCLEOS SON DIFERENTES PARA QUE LAS TRAYECTORIAS TENGAN DISTINTAS CONSTANTES DE PROPAGACION. EL VALOR DE ESTAS CONSTANTES COINCIDE PARA UNA LONGITUD DE ONDA DE ACOPLAMIENTO PREDETERMINADA. UNO DE LOS NUCLEOS INCLUYE UN MATERIAL FLUORESCENTE CAPAZ DE EMITIR BAJO UN ESTIMULO. SE DESCRIBE TAMBIEN UN METODO PARA AMPLIFICAR UNA SEÑAL OPTICA UTILIZANDO LA ESTRUCTURA DE FIBRA OPTICA DESCRITA, Y HACIENDO QUE LA LONGITUD DE ONDA (LAMBDA-S) DE LA SEÑAL OPTICA, LA LONGITUD DE ONDA FLUORESCENTE DEL MATERIAL DEL NUCLEO, Y LA LONGITUD DE ONDA DE ACOPLAMIENTO PREDETERMINADA SEAN APROXIMADAMENTE LAS MISMAS, INTRODUCIENDO UNA ENERGIA OPTICA CON UNA LONGITUD DE ONDA DIFERENTE (LAMBDA-P) EN DICHO NUCLEOPARA ACTIVAR EL MATERIAL FLUORESCENTE, Y EN EL OTRO NUCLEO PARA QUE LA SEÑAL OPTICA SE TRANSFIERA DE FORMA REPETIDA ENTRE AMBOS DEBIDO AL ACOPLAMIENTO OPTICO. CUANDO ESTA EN EL PRIMERO DE ELLOS PROVOCA LA AUTOESTIMULACION DEL MATERIAL FLUORESCENTE Y LA EMISION DE UNA ONDA CUYA LONGITUD ES APROXIMADAMENTE LA MISMA, POR LO CUAL SE AMPLIFICA. POR ULTIMO SE EXTRAE LA SEÑAL OPTICA AMPLIFICADA DE LA ESTRUCTURA DE FIBRA OPTICA CUANDO ESTA EN EL OTRO NUCLEO. TAMBIEN SE DESCRIBE UN APARATO PARA UTILIZAR ESTE METODO.
