Abstract
A multi-wavelength light source includes a laser, an optical modulator, an optical mixer, an optical demultiplexer, and an optical power adjuster that are sequentially coupled. The laser is configured to generate a first optical signal. The optical modulator modulates the first optical signal, to generate a second optical signal, where the second optical signal includes at least two wavelength components. The optical mixer mixes frequencies based on the at least two wavelength components to generate a third optical signal, where the third optical signal includes at least four wavelength components. The demultiplexer separates the at least four wavelength components. The optical power adjuster adjusts, based on a specified power threshold, a power of each of the wavelength components obtained by separation by the demultiplexer.
