Abstract

UN CONTROLADOR DE MODULACION LASER (10) MODULA LA OPERACION DE UN CIRCUITO LASER DE COMUNICACIONES Y CONTROLA LA ENTRADA ELECTRICA NRZ DENTRO DEL CIRCUITO LASER. EL CONTROLADOR DE MODULACION ELECTRICA COMPRENDE UN ACCIONADOR DE CIRCUITO LASER (20) PARA GENERAR Y EMITIR UNA SEÑAL DE ENTRADA AL CIRCUITO LASER (22). UN CIRCUITO DE CONTROL DE TENSION (18) CONTROLA EL ACCIONADOR DE CONTROL LASER (20) EN RESPUESTA A UNA ENTRADA SENCILLA (84). UN CIRCUITO DETECTOR DE TENSION DE PICO (2) RESPONDE A LA SALIDA DE TENSION DEL CIRCUITO DE ACCIONADOR (20) Y PRODUCE UNA SEÑAL DE TENSION DE PICO. UN CIRCUITO DE COMPARACION (82) COMPARA LA SEÑAL DE TENSION DE PICO CON UNA SEÑAL DE REFERENCIA (78 Y 70) Y PRODUCE A PARTIR D LA COMPARACION LA ENTRADA DE SEÑAL DE CONTROL (84) HACIA EL CIRCUITO DE CONTROL DE TENSION (18). EL CIRCUITO DE ENTRADA (84) DIRIGE LA SEÑAL DE CONTROL HACIA EL CIRCUITO DE CONTROL DE TENSION (18) PARA CONTROLAR EL ACCIONADOR DE CIRCUITO LASER (20).
