Controllable design of super-oscillatory lenses with multiple sub-diffraction-limit foci

Abstract The conventional multifocal optical elements cannot precisely control the focal number, spot size, as well as the energy distribution in between. Here, the binary amplitude-type super-oscillatory lens (SOL) is utilized, and a robust and universal optimization method based on the vectorial a...
