“…Other approaches used rigorous lamellar grating theory [24] and 3D ray tracing [9]. The most recent and accurate approaches utilize numerical methods like finite difference time domain (FDTD) for solving Maxwell's equations which can model the fine details of the structures [25][26][27][28]. Here, we apply a similar approach to model the complex butterfly structures using the finite element method (FEM) to solve Maxwell's equation with a commercial software package [29].…”

Abstract:Morpho butterflies are well-known for their iridescence originating from nanostructures in the scales of their wings. These optical active structures integrate three design principles leading to the wide angle reflection: alternating lamellae layers, "Christmas tree" like shape, and offsets between neighboring ridges. We study their individual effects rigorously by 2D FEM simulations of the nanostructures of the Morpho sulkowskyi butterfly and show how the reflection spectrum can be controlled by the design of the nanostructures. The width of the spectrum is broad (≈ 90 nm) for alternating lamellae layers (or "brunches") of the structure while the "Christmas tree" pattern together with a height offset between neighboring ridges reduces the directionality of the reflectance. Furthermore, we fabricated the simulated structures by e-beam lithography. The resulting samples mimicked all important optical features of the original Morpho butterfly scales and feature the intense blue iridescence with a wide angular range of reflection.

“…In the biological world, the colorful feathers of many birds (i.e., peacocks), the wings of various butterflies,and the elytra of many beetles are good examples of structural coloration 4, 8–11. Apart from the aforementioned properties, natural structural colors produced by these animals also give rise to additional optical properties.…”

In the biological world, numerous creatures such as butterflies, insects, and birds have exploited photonic structures to produce bicolor reflections with important biofunctions in addition to unique brilliant structural coloration. Although the mimicking of bistructural color reflection is possible, the fabrication involves a process of combined layer deposition techniques, which is complicated and less flexible. Here, a bistructural color mimicking, based on silk fibroin, is reported using a simple and inexpensive self‐assembly method. Silk‐fibroin inverse opals with different spectral positions of bistructural color reflection (i.e., ultraviolet and visible peaks, ultraviolet and near infrared peaks, and visible and near infrared peaks) are obtained by simply controlling their lattice constants. Furthermore, the inline and continuous tuning of the peak positions of bistructural color reflection can be achieved by the humidity‐induced cyclic contraction of silk fibroin. The potential applications of silk‐fibroin photonic structures in eco‐dying and multifunctional silk fabrics are also demonstrated.

“…The FDTD, which seeks the direct finite-difference solution of Maxwell's time-dependent curl equations, has been widely used for investigations into the mechanisms of structural color in Morpho butterflies [2,7,8]. Compared with the FDTD, rigorous coupled-wave analysis (RCWA) technique is a relatively straightforward technique for obtaining the exact solution of Maxwell's equations.…”

The micro/nano structures of the wing scales in Morpho butterfly are responsible for the structural coloration, with a major part ascribed to interference and diffraction of light. The optical properties of the butterfly wings were investigated by simulating a two-dimensional model using rigorous coupled-wave analysis technique. It is proved that they depend strongly on the structural parameters, incidence angle and refractive index. The peak value and the peak wavelength of the reflection efficiency increase as the vertical periodic thickness increases. The peak value decreases observably, while both of the bandwidth and the peak wavelength increase when the number of the vertical periods decreases. Increase of the horizontal periodic width causes a decrease of the peak value and an increase of the peak wavelength, although the variations are small. The peak value decreases distinctly and the peak wavelength increases as the ambient refractive index increases, which corresponds to the variation in ambient conditions. The research reveals the mechanisms of the brilliant structural color in Morpho butterfly, and is of great significance to the design, manufacture and applications of the bionic micro/nano structures for gas detection.
