Abstract

La presente invencion se refiere a un selector optico conmutado por ganancia, que se logra al emplear un amplificador optico de fibra adulterada con tierra rara optica como el elemento de conmutacion per se. Cada uno de los amplificadoresopticos de fibras adulteradas con tierras raras opticas, actua como un conmutador de ENCENDIDO/APAGADO. También, el selector optico conmutado de ganancia de esta invencion es un complemento natural en los sistemas de comunicaciones opticos amplificados opticamente en la actualidad. En una modalidad, esto se logra al emplear un circuito selector de bomba, en conjunto con una pluralidad de bombas y una pluralidad de amplificadores opticos de fibras adulteradas con tierras raras. La bomba particular y el amplificador optico correspondiente se elige por uso de una estructura de verificacion, para determinar que señal se va a seleccionar y dirigir a una salida. En otra modalidad, una estructura de bomba así denominada sintonizada se emplea en conjunto con una pluralidad de filtros y una pluralidad correspondientes de amplificadores opticos de fibras adulteradas con tierras raras. Una estructura de sintonizacion de bomba se emplea para controlar la bomba sintonizable a fin de seleccionar la apropiada de las señales de alimentacionopticas a cualquiera de una pluralidad de longitudes de onda determinadas.
