Abstract

SE PRESENTA UN SISTEMA AMPLIFICADOR DE FIBRA QUE INCLUYE UNA FIBRA DE GANANCIA QUE TIENE UN NUCLEO DE MODO SIMPLE DOPADO CON IONES DOPANTES ACTIVOS CAPAZ DE PRODUCIR UNA EMISION ESTIMULADA DE LUZ EN UNA LONGITUD DE ONDA LAMBDA SUB S CUANDO SE BOMBARDEA CON LUZ DE UNA LONGITUD DE ONDA LAMBDA SUB P. EMPALMADA A LA FIBRA DE GANANCIA SE ENCUENTRA UNA FIBRA ATENUADORA DE LA LUZ QUE TIENE UN NUCLEO QUE CONTIENE UN DOPANTE QUE ATENUA LA LUZ DE UNA LONGITUD DE ONDA LAMBDA SUB P PERO NO LA DE UNA LONGITUD DE ONDA LAMBDA SUB S. EL AMPLIFICADOR SE EMPLEA CONVENCIONALMENTE EN EL SISTEMA INCLUYENDO UNA FIBRA DE TELECOMUNICACIONES ENTRANTE PARA INTRODUCIR LUZ DE UNA LONGITUD DE ONDA LAMBDA SUB S DENTRO DE UN EXTREMO DE LA FIBRA DE GANANCIA, LA SEÑAL AMPLIFICADA SE CONECTA A UNA FIBRA DE TELECOMUNICACIONES SALIENTE. EL SISTEMA INCLUYE ADEMAS UNA FUENTE PARA INTRODUCIR LUZ DE UNA LONGITUD DE ONDA LAMBDA SUB P DENTRO DE UN EXTREMO DE LA FIBRA DE GANANCIA. LOS ELEMENTOS DEL SISTEMA PUEDEN ESTAR DISPUESTOS DEMANERA QUE BOMBEEN HACIA ADELANTE, BOMBEEN HACIA ATRAS O BOMBEEN POR AMBOS EXTREMOS. SE PRESENTAN VARIOS ESQUEMAS DE INTERCONEXION PARA FORMAR UNA DISPOSICION EN SERIE QUE INCLUYE LA FIBRA DE GANANCIA, LA FIBRA ATENUADORA Y LA FIBRA SALIENTE.
