Abstract

UN DISPOSITIVO DE AMPLIFICACION DE POLARIZACION INDEPENDIENTE QUE COMPRENDE UN AMPLIFICADOR SEMICONDUCTOR OPTICO. LA SEÑAL DE ENTRADA DEL DISPOSITIVO DE AMPLIFICACION SE INTRODUCE EN UN LADO DEL AMPLIFICADOR Y EN EL OTRO LADO SE SUMINISTRA UN REFLECTOR. LA SEÑAL DE SALIDA DEL DISPOSITIVO DE AMPLIFICACION, FORMADA POR LA SEÑAL DE ENTRADA DEL DISPOSITIVO DE AMPLIFICACION REFLEJADA POR EL REFLECTOR Y AMPLIFICADA POR EL AMPLIFICADOR, SE RECIBE EN EL PRIMER LADO DEL AMPLIFICADOR. EL REFLECTOR ES ALTERNATIVO, UNA SEÑAL O COMPONENTE DE SEÑAL INTRODUCIDA/O EN EL MISMO Y QUE TIENE UNA POLARIZACION PERPENDICULAR AL EJE PRINCIPAL QUE SE ESTA REFLEJANDO COMO SEÑAL DE REFLEXION QUE TIENE UNA POLARIZACION QUE ES VIRTUALMENTE PARALELA A DICHO EJE PRINCIPAL Y VICEVERSA.
