Abstract

The application provides an orbital angular momentum and wavelength dual multiplexing polarization sensitive zooming super lens based on an orbital angular momentum and wavelength dual multiplexing polarization sensitive zooming super lens, characterized in that the super lens is composed of a silicon dioxide substrate layer and a silicon elliptical nanometer column medium layer. Through an orbital angular momentum topological charge number orthogonality and wavelength selectivity dual multiplexing mechanism, combined with a polarization sensitive design, a geometric phase regulation mechanism, the silicon elliptical nanometer column array is optimized through size and rotation angle, 0-2pi full phase coverage is realized, different orbital angular momentum modes, different wavelengths and left-handed / right-handed circularly polarized incident light are precisely demultiplexed in a 400-700nm visible light band, multi-channel independent zooming can be realized, and the focusing efficiency is greater than or equal to 65%. The application solves the defects of single zooming function, limited channel capacity and poor polarization compatibility of the traditional super lens, has compact structure and high integration, and can be widely applied to the fields of miniature imaging systems, optical communication, holographic display and the like.
