Scalable switched slab coupler based optical phased array on silicon nitride

Autor: Muñoz, Pascual, Pastor, Daniel, Bru, Luis A., Micó, Gloria, Benítez, Jesús, Goodwill, Dominic J., Bernier, Eric

A two-dimensional optical-phased array is demonstrated by using a multiple-input star coupler, compatible with FMCW LiDAR. Previous approach using a single-input design achieves two-dimensional beam-steering by relying on a tunable laser source, taki

Autor: Mayoral Astorga Luis Angel, Shabaninezhad Masoud, Northfield Howard, Ntais Spyridon, Rashid Sabaa, Lisicka-Skrzek Ewa, Mehrvar Hamid, Bernier Eric, Goodwill Dominic, Ramunno Lora, Berini Pierre

Publikováno v: Nanophotonics, Vol 13, Iss 6, Pp 901-913 (2024)

We report the fabrication and characterization of a plasmonic metasurface comprising electrically-contacted sub-wavelength gold dipole nanoantennas, conformally coated by a thin hafnia film, an indium tin oxide layer and a backside mirror, forming me

On the performance of optical phased array technology for beam steering

Autor: Lesina, Antonio Cala', Goodwill, Dominic, Bernier, Eric, Ramunno, Lora, Berini, Pierre

Optical phased arrays are of strong interest for beam steering in telecom and LIDAR applications. A phased array ideally requires that the field produced by each element in the array (a pixel) is fully controllable in phase and amplitude (ideally con

Optical phased arrays for LIDAR: beam steering via tunable plasmonic metasurfaces

Autor: Lesina, Antonino Calà, Goodwill, Dominic, Bernier, Eric, Ramunno, Lora, Berini, Pierre

Controlling the phase and amplitude of light emitted by the elements (i.e., pixels) of an optical phased array is of paramount importance to realizing dynamic beam steering for LIDAR applications. In this paper, we propose a plasmonic pixel composed
