Beam steering with dielectric metalattices [PDF]
ACS Photonics, 2017 We study optical wave manipulations through high-index dielectric metalattices in both diffractionless metasurface and diffractive metagrating regimes. It is shown that the collective lattice couplings can be employed to tune the excitation efficiencies ...

Arrayed waveguide lens for beam steering. [PDF]
Nanophotonics, 2022 Abstract Integrated planar lenses are critical components for analog optical information processing that enable a wide range of applications including beam steering. Conventional planar lenses require gradient index control which makes their on-chip realization challenging. Here, we introduce a new approach for beam steering by designing
