We propose a single phase-only optical element that transforms different orbital angular
momentum (OAM) modes into localized spots at separated angular positions on a transverse …

… The time-averaged electric energy density near the focus of a parabolic mirror of wide-angular
aperture is calculated and compared with that of an aplanatic lens system. The …

… In the automotive field, wide-angle lenses are important for … -angle lenses could provide
clearer image quality than panoramic lenses do that both wide-angle lenses and fish-eye lenses …

… angular momentum (OAM) multiplexing systems. In this letter, a coaxial separation and
convergence scheme for multiple OAM modes is proposed based on a compound angular lens (…

… Luneburg lenses have superior performance compared with conventional lenses made of
uniform … Recently, a new two-dimensional (2D) imaging lens was proposed and realized using …

… We have analyzed in detail abilities of lenses with the radial and angular modulation for …
lens transmittance as well as the light sword optical element representing a lens with angular …

… We have designed and demonstrated a single-element wide-angle lens with a field of view
