摘要: Embodiments of the present disclosure disclose a modulator, including: a first modulation module, configured to: receive first to-be-modulated data, and output a first transmission curve according to the first to-be-modulated data; a second modulation module, configured to: receive second to-be-modulated data, and output a second transmission curve according to the second to-be-modulated data, where a period of the second transmission curve is half of a period of the first transmission curve; and a combination module, configured to perform phase superposition on the first transmission curve and the second transmission curve, to obtain a combined linear result. In addition, this solution further provides a modulation system and a method for implementing higher order modulation, so that a linear result that can be modulated can be obtained by controlling a superposition ratio between transmission curves, to implement linear curve transmission.

摘要: A first optical splitter splits a light source to obtain a first optical signal, a second optical signal, and a third optical signal. A first MZ modulator modulates the first optical signal to output a fourth optical signal. A second MZ modulator modulates the second optical signal to output a fifth optical signal. A first optical coupler couples the fourth optical signal and the fifth optical signal to output a sixth optical signal and a seventh optical signal. A power regulator and a phase shifter respectively perform power adjustment and phase shifting on the third optical signal to output an eighth optical signal. A second optical splitter splits the eighth optical signal into a ninth optical signal and a tenth optical signal. A second optical coupler combines the sixth optical signal and the ninth optical signal. A third optical coupler combines the seventh optical signal and the tenth optical signal.
