Abstract

SE DESCRIBE UN AMPLIFICADOR OPTICO PERFECCIONADO CON EFECTOS NOCIVOS REDUCIDOS, INDUCIDOS POR SEÑAL, DE ALINEALIDAD, COMO INTERFERENCIAS, DISTORSION DE INTERMODULACION Y OTRS EFECTOS INDUCIDOS POR SATURACION. EL INVENTO CONSTA DE UN AMPLIFICADOR OPTICO CON UN CIRCUITO DE COMPENSACION, COMO UN CIRCUITO ALIMENTADOR O RETROALIMENTADOR. ESTE CIRCUITO PROPORCIONA UN BOMBEO ADICIONAL AL MEDIO DE GANANCIA ASOCIAD CON EL AMPLIFICADOR, Y, EN CONSECUENCIA, COMPENSACION DE LO QUE, EN OTRO CASO, SERIAN VARIACIONES NOCIVAS.
