Abstract

The invention discloses an infrared all-dielectric orthogonal cylindrical surface super lens, relates to the technical field of long-wave infrared imaging, and solves the problems that a long-wave infrared system is low in transmittance, large in energy loss and complex in processing technology. Comprising a light-transmitting substrate, a first sub-wavelength array structure arranged on one side of the light-transmitting substrate and a second sub-wavelength array structure arranged on the other side of the light-transmitting substrate, and the first sub-wavelength array structure and the second sub-wavelength array structure can converge light. The convergence directions of the first sub-wavelength array structure and the second sub-wavelength array structure are perpendicular to each other; and the phase of the infrared all-dielectric orthogonal cylindrical surface super lens is as follows: lambda is incident light wavelength, and f is focusing focal length. According to the invention, the long-wave infrared single-wavelength metasurface lens is realized, the number of lenses of a long-wave infrared system is reduced, the transmittance is high, the energy loss is small, and the processing technology is relatively simple.

Description

technical field [0001] The invention relates to the technical field of long-wave infrared imaging, in particular to an infrared all-medium orthogonal cylindrical superlens. Background technique [0002] Metalens are a hot research direction in micro-nanostructured metasurfaces. Metalens use subwavelength micro-nano structures to control the wavefront of light. Based on its super-strong manipulation ability of light waves, it has the advantages of ultra-light, ultra-thin, and easy integration. It has become a hot spot in optical research and is expected to be used for nano-optical imaging and Ultra-miniature optoelectronic devices blaze a new path. In recent years, the research on metalens in the visible and near-infrared bands has developed well, and single-wavelength, multi-wavelength and broadband achromatic metalens in the visible light band have been realized. But for now, there are still few studies on metalens in the long-wave infrared band. [0003] Long-wave infra...
