1. A multi-wavelength cluster light source comprising:
a first light source, an optical multiplexer, a first optical splitter, an optical amplifier array and an optical switch array, wherein
the first light source is used to output a plurality of single-wavelength continuous-wave light in parallel,
wherein wavelengths of the plurality of single-wavelength continuous-wave light are different;
the optical multiplexer is configured to combine the plurality of single-wavelength continuous-wave light into one first multi-wavelength continuous-wave light, including combining a plurality of single-wavelength continuous-wave light selected and output by the optical switch array into the first multi-wavelength continuous-wave light;
the first optical splitter is configured to perform power beam splitting on the first multi-wavelength continuous-wave light, to output a plurality of second multi-wavelength continuous-wave light;
the optical amplifier array is used to amplify the plurality of second multi-wavelength continuous-wave light, to output a plurality of third multi-wavelength continuous-wave light;
the optical switch array is used to receive the plurality of single-wavelength continuous-wave light and a plurality of other single-wavelength continuous-wave light output by a second light source,
wherein wavelengths of the plurality of other single-wavelength continuous-wave light are in a one-to-one correspondence with the wavelengths of the plurality of single-wavelength continuous-wave light,
wherein a quantity of optical switches comprised in the optical switch array is equal to a quantity of the plurality of single-wavelength continuous-wave light, and
wherein each optical switch of the optical switch array is used to select any one of two single-wavelength continuous-wave light having a same wavelength in the plurality of single-wavelength continuous-wave light or in the plurality of other single-wavelength continuous-wave light, to input the selected single-wavelength continuous-wave light into the optical multiplexer.
