摘要

我们报道了在光通信波长实现二次相位轮廓的消色差超构透镜的设计。光束准直和转向在±40°的宽视场是实现的。此外，在100 nm波长范围内证明了波长无关聚焦。

Silicon-based broadband metalens for wide-angle optical beam steering

We report on the design of an achromatic metalens at optical communication wavelengths implementing a quadratic phase profile. Beam collimation and steering over a wide field of view of ±40° is achieved. Moreover, wavelength-independent focusing is demonstrated over a 100 nm wavelength range.
