摘要

生产具有亚波长特征的平面光学器件,尤其是在可见光频率下,仍然是一项重大挑战。在这里,我们建立了一个设计有效介质元表面(EMM)的框架,依靠介孔硅的纳米压印来实现与任意透射相位轮廓j(x,y)相对应的图案化折射率n(x,y)。该方法用于设计生产菲涅尔透镜所需的印章轮廓,并使用有限差分时域法检验了金属透镜的理论性能。此外,我们还演示了神经网络辅助蒙特卡洛分析法,该方法可用于模拟元表面制造误差对 EMM 性能和工艺产量的影响。

Effective medium metasurfaces using nanoimprinting of the refractive index: design, performance, and predictive tolerance analysis
Production of flat optics incorporating subwavelength features, particularly at visible frequencies, remains a significant challenge. Here, we establish a framework for the design of effective medium metasurfaces (EMM), relying on nanoimprinting of mesoporous silicon to realize a patterned refractive index n(x,y) corresponding to an arbitrary transmitted phase profile ϕ(x,y). The method is used to design the stamp profile required to produce a Fresnel lens and the theoretical performance of the metalens is examined using the finite-difference time-domain method. Additionally, we demonstrate neural network aided Monte Carlo analysis as a method to model the effects of metasurface fabrications errors on EMM performance and process yield.

期刊介绍: The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optical Materials Express (OMEx), OSA''s open-access, rapid-review journal, primarily emphasizes advances in both conventional and novel optical materials, their properties, theory and modeling, synthesis and fabrication approaches for optics and photonics; how such materials contribute to novel optical behavior; and how they enable new or improved optical devices. The journal covers a full range of topics, including, but not limited to: Artificially engineered optical structures Biomaterials Optical detector materials Optical storage media Materials for integrated optics Nonlinear optical materials Laser materials Metamaterials Nanomaterials Organics and polymers Soft materials IR materials Materials for fiber optics Hybrid technologies Materials for quantum photonics Optical Materials Express considers original research articles, feature issue contributions, invited reviews, and comments on published articles. The Journal also publishes occasional short, timely opinion articles from experts and thought-leaders in the field on current or emerging topic areas that are generating significant interest.
