Abstract
Se describe un sistema de modulacion analogico, que comprende un modulador electrooptico, con una doble salida y un circuito conductor. En particular, elsistema comprende una fuente optica, un modulador electrooptico, una senal eléctrica demodulacio n y un circuito conductor para dicho modulador electrooptico,dicho modulador electrooptico tiene dos salidas opticas, que proporcionan una primera y una segunda senales opticas moduladas, que se complementan entre sí,cada una de dichassalidas optica s de dicho modulador se encuentra conectada a un acoplador optico que tiene una ramificacion que proporciona una porcion de lasenal optica modulada y también está conectada a un receptor optico, que tiene capacidad de generar unaprimera y una segund a senales eléctricas de control,segun corresponde, en respuesta a una primera frecuencia de dichas primera y segunda senales opticas moduladas analogicas, donde el circuito conductor al quese hace referencia comprende uncircuito que genera una senal eléctrica piloto en una segunda frecuencia, que es igual a la mitad de la citada primerafrecuencia, que se agrega a dicha senal eléctrica de modulacion; un circuito de conversion que puede producir una senal convertidade manera continua que espropo rcional a la diferencia de amplitud que existe entre las citadas primera y segunda senales eléctricas de control; y un circuito de polarizacion que puedegenerar una senal de polarizacion en respuesta a dicha senal decontrol.An analog modulation system is described, comprising an electro-optic modulator, with a double output and a conductor circuit. In particular, the system comprises an optical source, an electro-optic modulator, an demodulation electrical signal and a conductive circuit for said electro-optic modulator, said electro-optic modulator has two optical outputs, which provide a first and second modulated optical signals, which complement each other. , each of said optical outputs of said modulator is connected to an optical coupler that has a branch that provides a portion of the modulated optical signal and is also connected to an optical receiver, which has the capacity to generate a first and a second to electrical signals control, as appropriate, in response to a first frequency of said first and second analog modulated optical signals, where the conductive circuit referred to comprises a circuit that generates a pilot electrical signal at a second frequency, which is equal to half of said first frequency, which is added to said signal on modulation electrics; a conversion circuit that can produce a continuously converted signal that is proportional to the difference in amplitude that exists between said first and second electrical control signals; and a polarization circuit that can generate a polarization signal in response to said control signal.
