Example Embodiment

[0050]In the following, the embodiments of the present invention will be described with reference to the accompanying drawings. It should be understood that the following embodiments are only used to illustrate the present invention, but not to limit the scope of the present invention.

[0051]Such asfigure 1 withfigure 2 As shown, a polarization-independent super lens includes a substrate layer and a super surface layer for realizing geometric phase modulation.

[0052]The array of the super surface layer is designed with a 10*10 structure, and the designed focal length is 4um. For left-handed circularly polarized light or right-handed circularly polarized light of any phase, a row of unit structures is generated, and the left-handed and right-handed circularly polarized light structures of the same phase are arranged symmetrically.

[0053]Such asimage 3 with4 As shown, the unit structure of the super-surface layer uses gallium nitride material, and the substrate layer uses SiO 2 Glass; Am...

Abstract

The invention discloses a polarization-independent super lens and a design method thereof. The polarization-independent super lens comprises a substrate layer and a metasurface layer for realizing geometric phase modulation; the metasurface layer comprises a plurality of unit structures for realizing convergence of left-handed circularly polarized light and a plurality of unit structures for realizing convergence of right-handed circularly polarized light, and the plurality of unit structures for realizing convergence of left-handed circularly polarized light and the plurality of unit structures for realizing convergence of right-handed circularly polarized light are arranged in a crossed manner; geometric phase modulation is achieved through the unit structures without rotational symmetry. Polarization-independent convergence is achieved, incident light of any polarization can be converged, and polarization processing does not need to be conducted on the incident light.

Description

technical field [0001] The invention relates to the technical field of hyperlens imaging, in particular to a polarization-independent hyperlens and a design method thereof. Background technique [0002] As a key component of the imaging system, optical lenses are widely used in many fields such as scientific research, life, medical treatment, and national defense. In the development of modern optical systems, traditional optical lenses are facing many insurmountable challenges: First, the adjustment of the wavefront of the incident beam by optical lenses is based on the gradual accumulation of phase during light transmission, so it is limited by the refractive index and At the same time, in order to correct various aberrations, multiple lenses need to be designed in combination, which further increases the volume of the optical system and hinders the development of miniaturization of modern optoelectronic devices. Second, the manufacturing process of optical lenses needs to...
