Abstract

SE PROPONEN RECEPTORES DE SUPERPOSICION OPTICOS PARA SEÑALES MODULARES ASK, PSK, FSK Y DPSK, QUE CONTIENEN UN DISPOSITIVO DE REGULACION DE POLARIZACION. EL RECEPTOR CONTIENE UN DISPOSITIVO (Q, Q'', Q") QUE TRABAJA SEGUN EL CONCEPTO DETECTOR DE DIFERENCIA PARA SUBPRESION DE RUIDOS DE INTENSIDAD DEL OSCILADOR LOCAL (LO), QUE EMITE LUZ POLARIZADA CIRCULAR. CONTIENE ADEMAS UN DEMODULADOR DE CUADRATURA (D, D'', D") QUE EMITE ADEMAS DE LA SEÑAL UTIL (N) TAMBIEN LA SEÑAL DE REGULACION (SE, SW) PARA REGULACION DE LA POLARIZACION, POR LA QUE SE REGULA LA ELIPTICIDAD Y EL ANGULO DE LA POLARIZACION DE LA LUZ DEL RECEPTOR. ES, DE TAL MODO QUE LA LUZ DEL RECEPTOR ES SE POLARIZA BAJO UN ANGULO DE 45 O DE 135 LINEALMENTE.
