Journal ArticleDOI
Arbitrary spin-to–orbital angular momentum conversion of light
TL;DR: A metasurface converter for optical states that transforms polarization states into optical angular momentum states and illustrates a general material-mediated connection between SAM and OAM of light and may find applications in producing complex structured light and in optical communication.
Journal ArticleDOI
Broadband and chiral binary dielectric meta-holograms.
TL;DR: This is a study of basic holographic principles in designing new nanostructured devices that enable broadband and chiral imaging and demonstrates chiral holograms that project different images depending on the handedness of the reference beam by incorporating a geometric phase.
Journal ArticleDOI
Light-induced spiral mass transport in azo-polymer films under vortex-beam illumination
TL;DR: A model that explains the main features of this phenomenon through the surface-mediated interference of the longitudinal and transverse components of the optical field is proposed and may find applications in optical nanolithography and optical-field nanoimaging.
Journal ArticleDOI

TL;DR: In this paper, a van der Waals crystal, α-MoO3, is shown to support in-plane hyperbolic polariton guided modes at mid-infrared frequencies without the need for patterning.
Journal ArticleDOI
High-purity orbital angular momentum states from a visible metasurface laser
