Abstract: Embodiments of the present application provide an optical signal generation device. The device includes a laser, a first modulator, a second modulator, a first adjustment module, and a beam combiner. The laser is configured to: output a first optical signal to the first modulator, and output a second optical signal to the second modulator. The two modulators are separately configured to: receive an optical signal and a loaded electrical modulation signal, and modulate the optical signal based on the electrical modulation signal, to obtain a first modulated optical signal and a second modulated optical signal. The first adjustment module is further configured to adjust a phase of the modulated optical signal or an optical path to the beam combiner. The beam combiner is configured to: combine the first modulated optical signal obtained after the adjustment and the second modulated optical signal, and output a combined signal.

Abstract: Embodiments of the present invention provide an optical signal modulation apparatus and system. The optical signal modulation apparatus includes: a laser, where each of at least one first output end and at least one second output end of the laser is connected to an electro-absorption modulator (EAM); the laser is configured to generate at least two optical signals, where at least one of the optical signals is sent to at least one EAM by using the at least one first output end, and at least one of the optical signals is sent to at least one EAM by using the at least one second output end; and each EAM is configured to modulate a received electrical signal onto the received optical signal for outputting. The apparatus has a simple structure, and less complex production.
