“…Each micromirror could serve as a wavelength-selective spatial light modulator, optimized for small form-factor applications and with highly flexible light patterns. Such micromirrors are desirable for fiber optics or optical switching [77][78][79], where micromirror technology will be essential for increasing the speed of communication. For example, when information needs to be re-routed to a personal computer.…”

“…Planar compound eye structures are characterized by thousands of closely interconnected planar micro-lenses, densely arranged and uniformly distributed on a planar substrate [35][36][37][38]. In contrast, curved compound eye structures emulate the architecture of biological compound eyes, featuring a closely connected array of hexagonal micro-lenses arranged on a curved substrate [2,7,39,40]. As micro-optical systems continue to advance and the utilization of compound eye structures becomes more prevalent, there is a growing emphasis on exploring micro-nanofabrication techniques.…”

Over millions of years of evolution, arthropods have intricately developed and fine-tuned their highly sophisticated compound eye visual systems, serving as a valuable source of inspiration for human emulation and tracking. Femtosecond laser processing technology has attracted attention for its excellent precision, programmable design capabilities, and advanced three-dimensional processing characteristics, especially in the production of artificial bionic compound eye structures, showing unparalleled advantages. This comprehensive review initiates with a succinct introduction to the operational principles of biological compound eyes, providing essential context for the design of biomimetic counterparts. It subsequently offers a concise overview of crucial manufacturing methods for biomimetic compound eye structures. In addition, the application of femtosecond laser technology in the production of biomimetic compound eyes is also briefly introduced. The review concludes by highlighting the current challenges and presenting a forward-looking perspective on the future of this evolving field.

“…The mold is formed by photo-polymerization, and the resultant shrinkage, of polyacrylamide (PAAm) hydrogel. Finally, Huang et al [8] present a wide-angle, broad-spectrum cylindrical lens based on reflections from a micro-mirror array, rather than refraction. This intriguing mechanism is inspired by the reflecting superposition compound eyes of some decapods.…”

The study and application of microscale lenses and lens arrays have been actively researched in recent years; new approaches in the fabrication of microlenses and microlens arrays have emerged. Also, novel applications of these microlenses and microlens arrays have been demonstrated. In an effort to disseminate the current advances in this specialized field of microlenses and microlens arrays, and to encourage discussion on the future research directions while stimulating research interests in this area, a Special Issue of Micromachines has been dedicated to "Microlenses".This Special Issue presents a total of ten papers covering most of the active areas of research in microlenses and microlens arrays. Specifically, eight papers are on the fabrication and characterization of microlenses and microlens arrays, one focuses on integration of microlenses into complex micro-optical modules, and the last one deals with the super-hydrophobic surface that is often important to realize droplet-based microlenses.The fabrication and realization of microlenses and microlens arrays reported in these papers, cover a wide range of mechanisms, technologies, materials, and optical designs. Xu et al.[1] provide a thorough review of how to improve the response time of liquid crystal (LC) based tunable-focus microlenses. The basic operating principles and recent progress are introduced and reviewed for two types of fast-response microlenses based on LC/polymer composites: polymer dispersed/stabilized nematic LC and polymer-stabilized blue phase LC. Chen et al. [2] propose a polarization independent LC microlens arrays based on controlling the spatial distribution of the Kerr constants of blue phase LC; the concept is supported by simulation. Two papers are on adaptive liquid lenses actuated via electrowetting. Liu et al.
