“…showed that the dispersion of phase shift could also be designed to achieve good focusing properties with the same focal length at several discrete wavelengths or even in a broadband spectrum 26 27 . Besides the achromatic focusing, it should also be noted that the metasurface-enabled multi-focus lens can also find promising applications in high-capacity data-storage 28 .…”

The independent control of electromagnetic waves with different oscillating frequencies is critical in the modern electromagnetic techniques, such as wireless communications and multispectral imaging. To obtain complete control of different light waves with optical materials, the chromatic dispersion should be carefully controlled, which is however extremely difficult. In this paper, we propose a method to control the behaviors of different light waves through a metasurface which is able to generate achromatic geometric phase. Using this approach, a doughnut-shaped and a solid light spot were achieved at the same focal plane using two light sources with different wavelengths as used in the stimulation emission depletion (STED) microscope system. In order to reveal the full capacity of such method, tight focusing at multiple wavelengths is also represented, where the focal spots of different wavelengths are located at the same position. The results provided here may open a new door to the design of subminiature optical components and integrated optical system operating at multiple wavelengths.

In the past centuries, the scale of engineering optics has evolved toward two opposite directions: one is represented by giant telescopes with apertures larger than tens of meters and the other is the rapidly developing micro/nano‐optics and nanophotonics. At the nanoscale, subwavelength light–matter interaction is blended with classic and quantum effects in various functional materials such as noble metals, semiconductors, phase‐change materials, and 2D materials, which provides unprecedented opportunities to upgrade the performance of classic optical devices and overcome the fundamental and engineering difficulties faced by traditional optical engineers. Here, the research motivations and recent advances in subwavelength artificial structures are summarized, with a particular emphasis on their practical applications in super‐resolution and large‐aperture imaging systems, as well as highly efficient and spectrally selective absorbers and emitters. The role of dispersion engineering and near‐field coupling in the form of catenary optical fields is highlighted, which reveals a methodology to engineer the electromagnetic response of complex subwavelength structures. Challenges and tentative solutions are presented regarding multiscale design, optimization, fabrication, and system integration, with the hope of providing recipes to transform the theoretical and technological breakthroughs on subwavelength hierarchical structures to the next generation of engineering optics, namely Engineering Optics 2.0.

“…Dynamic ultrafast fabrication by superresolved multifocal arrays has been proposed and demonstrated by combining the SPIN and multifocal arrays methods (Figure 7e). [137] Both the writing and inhibition beam in the SPIN system were expanded to two multifocal arrays through accurate phase modulation, respectively. With the superposition of the two multifocal arrays in the focal plane, superresolved multifocal array could be achieved for parallel fabricating nanostructures.…”

Controlled microstructural architectures-artificially designed microstructures and nanostructures with controlled properties-have been extensively used in scientific research and practical applications. Advanced fabrication strategies are always desired to satisfy the increasing demands for specific architecture designs. This review highlights recent progress of bottom-up methods based on selfassembly and top-down methods by using two-photon polymerization. As an emerging additive manufacturing technology, two-photon polymerization has shown the enormous potential of being a general fabrication method for controlled microstructural architectures due to its unique advantage in direct laser writing of three-dimensional microstructures with high resolution. This review also covers some remaining challenges for controlled microstructural architectures, along with future outlooks.
