In summary, we employ the genetic algorithm optimization to arbitrarily manipulate the chromatic dispersion based on metalenses, and then we design the metalens-based color router in the near infrared region. Finally, we show the multifunctional structured light generator that can modulate more complex phase profiles at different wavelengths. Additionally, the meta-devices in this work possess a polarization-independent property due to the phase library consisting of centrosymmetric nanopillars. Metalens based on the optimization algorithm can not only allow multiple functions by utilizing the dimension of wavelength, but also have the merits of miniaturization and integration, which are expected to apply in the next generation of optical platform. We also anticipate that wavelength-multiplexing multifunctional metalenses have greater potential in computer science.
