Abstract
The present invention discloses an optical modulation device, which comprises an electric signal generator generating an electric signal carrying a data signal; a first sinusoidal signal generator generating a first sinusoidal signal; an optical signal generator generating an input source optical signal; and an optoelectronic modulator (Mach-Zehnder modulator) receiving the input source optical signal, the electric signal and the first sinusoidal signal, biased to modify a transmission performance of the input source optical signal, modulating the input source optical signal with the electric signal and the first sinusoidal signal, and then sending out an output source optical signal carrying the electric signal and the first sinusoidal signal. The present invention realizes frequency multiplication, enables an optical signal to carry vector signals, and promotes the efficiency of broadband systems.
