The paper presents a novel approach to achieving multi-wavelength achromatic behavior in metasurfaces, which are thin, planar optical components. The authors demonstrate that by engineering a wavelength-dependent phase shift through the use of low-loss dielectric resonators, chromatic aberrations can be effectively compensated. This design allows for the deflection of light at multiple wavelengths without dispersion, addressing a key limitation of both refractive and diffractive optics. The metasurface is composed of coupled rectangular dielectric resonators (RDRs) arranged in a non-periodic pattern, enabling continuous control of the phase profile. The design is validated through simulations and experiments, showing that the metasurface can deflect light at three different telecom wavelengths (1300 nm, 1550 nm, and 1800 nm) with the same angle of deflection (-17°). Additionally, the authors present a flat lens design based on RDRs that corrects chromatic aberrations for these three wavelengths, achieving near-diffraction limit focusing. The metasurface's versatility and potential for broadband operation make it a promising candidate for applications in digital cameras, holographic 3D displays, and compact integrated devices for nonlinear processes.The paper presents a novel approach to achieving multi-wavelength achromatic behavior in metasurfaces, which are thin, planar optical components.
