Abstract: A dummy light signal generation apparatus, which can be used in the communication field. The apparatus includes: a light source module configured to generate a first wavelength signal and a second wavelength signal, where the first wavelength signal has N first channels, and the second wavelength signal has M second channels; and a polarization beam combiner configured to polarize and combine the first wavelength signal and the second wavelength signal to output a dummy light signal, where the dummy light signal has N+M channels. A polarization state of a wavelength signal of a dummy light signal on any first channel is orthogonal to a polarization state of a wavelength signal of the dummy light signal on the second channel.

Abstract: A multi-wavelength laser and a wavelength control method are disclosed. The multi-wavelength laser includes a waveguide, a first electrode, and a second electrode. The first electrode and the second electrode are disposed on the waveguide. The first electrode is electrically isolated from the second electrode. The first electrode includes a plurality of sub-electrodes, and every two adjacent sub-electrodes are electrically isolated. The second electrode is configured to amplify an optical signal in the waveguide by loading a current. At least one sub-electrode is configured to adjust a wavelength of the optical signal in the waveguide by loading a current or a voltage.
