摘要:

光学系统中多重像差的校正需要不同的光学元件,这增加了其成本和复杂性。超颖表面在为小型化和低成本光学系统提供新功能方面具有很大的潜力。相对于它们的大块对应物的一个关键优势是超颖表面响应光的偏振的能力,这为光学设计增加了一个新的自由度。在这里,我们表明,偏振控制使一个形式的双折射超透镜,以纠正球面和离轴像差仅使用一个单一的元素,这是不可能与散装光学。超透镜将两个相位轮廓编码到同一表面上,从而允许从高分辨率切换到宽视场操作。这种在单层中获得高分辨率和宽视场的能力是朝向小型化光学系统集成的重要一步,其可以找到许多应用,例如,显微镜和内窥镜检查。

英文摘要:

The correction of multiple aberrations in an optical system requires different optical elements, which increases its cost and complexity. Metasurfaces hold great promise to providing new functionality for miniaturized and low-cost optical systems. A key advantage over their bulk counterparts is the metasurface's ability to respond to the polarization of light, which adds a new degree of freedom to the optical design. Here, we show that polarization control enables a form-birefringent metalens to correct for both spherical and off-axis aberrations using a single element only, which is not possible with bulk optics. The metalens encodes two phase profiles onto the same surface, thus allowing switching from high resolution to wide field of view operation. Such ability to obtain both high resolution and wide field of view in a single layer is an important step towards integration of miniaturized optical systems, which may find many applications, e.g., in microscopy and endoscopy.
