  • Objective

    As a new type of planar optical element, meta-lens can flexibly control the phase, polarization and amplitude of light. They have great potential for device lightweighting and mass manufacturing, and have garnered widespread attention. Off-axis meta-lens, a special type of meta-lens with certain dispersion effect, can be used as a spectral element, providing a unique and feasible way to realize micro instruments. This paper proposes a design method for off-axis meta-lens and analyzes the effects of numerical aperture, off-axis angle, and incident wavelength on the simulation deviation, resolution and focusing efficiency of off-axis meta-lenses, which provides valuable insights for subsequent research and application of off-axis meta-lenses.

    Methods

    Several off-axis meta-lenses with parameters NA =0.408 α =13°, NA =0.18 α =13°, NA =0.408 α =20° were simulated by Lumerical, respectively.

    Results

    The simulation results indicate that the off-axis angle is directly proportional to the spectral resolution. As the angle increases, t the spectral resolution becomes larger, but the focusing efficiency decreases. A smaller numerical aperture result in a smaller coverage of the phase distribution, leading to a larger deviation between the simulation and theory.

    Conclusion

    Designers need to reasonably balance parameters such as numerical aperture and off-axis angle according to the requirements to finally achieve the desired effect. The conclusion of this study is an important reference value for theoretical analysis and parameter design of off-axis meta-lens in practical application.
