Abstract
SE DESCRIBE UN MODULADOR OPTICO EXTERNO (18,64,120,150) QUE SE HACE LINEAL PARA REDUCIR DISTORSIONES DE SEGUNDO ORDEN. UN PORTADOR OPTICO SE MODULA EN EL MODULADOR MEDIANTE UNA SEÑAL PILOTO (38). EL PORTADOR OPTICO MODULADO SE MUESTRA (26) Y SE GENERA UNA SEÑAL DE ERROR INDICATIVA DE LA DIFERENCIA DE FASE ENTRE UNA SEGUNDA ARMONICA DE LA SEÑAL PILOTO Y SUS ARMONICAS DE SEGUNDO ORDEN PRESENTES EN EL PORTADOR OPTICO MODULADO EN MUESTRA. LA SEÑAL DE ERROR REGRESA (42,56) AL MODULADOR (18) PARA AJUSTAR SUS VIAS HASTA MINIMIZAR LA DIFERENCIA DE FASE Y ASI MINIMIZAR LAS DISTORSIONES DE SEGUNDO ORDEN PRODUCIDAS POR EL MODULADOR. CUANDO VARIOS MODULADORES EXTERNOS (65,67) SE OPERAN EN SERIES, CADA UNO TIENE UN ANILLO DE RETROALIMENTACION (76-82,84-90) PARA MINIMIZAR LAS DISTORSIONES DE SEGUNDO ORDEN EN EL PRODUCIDAS.
