Abstract

This paper proposes a two-dimensional tunable metasurface beam deflector utilizing the electro-optic effect of lead lanthanum zirconate titanate (PLZT) thin films.Theoretical calculations and simulation have verified that the regular variation of applied voltage can form a continuous phase gradient on the metasurface, thereby achieving adjustable two-dimensional beam deflection or scanning. Compared to the non tunability of traditional metasurfaces, the design in this paper can achieve continuous scanning of the beam at large angles in two dimensions. The results show that the designed beam deflector can achieve large angle deflection at a wavelength of 1.064μm, with a deflection angle greater than 13°and an optical efficiency greater than 90 %. The tunable metasurface beam deflection technology designed in this article is expected to be applied as a laser scanning device in fields such as optical communication, LiDAR, and laser guidance, and has certain reference significance for designing multifunctional beam control.
