When biological photonic crystals are discussed, butterfly photonic crystals are often cited as representative; in fact, numerous diverse biological photonic crystals exist and butterfly photonic crystals have several quirks when compared with others, with the consequence that considering them typical is in many ways unhelpful. In this paper, we give an overview of biological photonic crystals and discuss their typical features, specifically with regard to their periodicities, geometries… 

Light Manipulation by Guanine Crystals in Organisms: Biogenic Scatterers, Mirrors, Multilayer Reflectors and Photonic Crystals

Guanine crystals are widely used in nature to manipulate light. The first part of this feature article explores how organisms are able to construct an extraordinary array of optical “devices”

Fundamentals of Photonic Crystal Guiding

In this systematic, rigorous, and pedagogical introduction to photonic crystals, intuitive analytical and semi-analytical models applied to complex and practically relevant photonic crystal structures are presented.

Natural slab photonic crystals in centric diatoms

It is shown that the girdle of the centric diatom Coscinodiscus granii is a well-defined slab photonic crystal, causing, under more natural conditions when immersed in water, a pseudogap for modes in the near infrared, which disperses towards the visible spectral range when light incides at larger angles.

Photonic crystals: a unique partnership between light and matter

Photonic crystals are periodic dielectric structures with an index of refraction periodicity of the order of the wavelength of light. They are emerging as a key building block for many applications

Photonic nanoarchitectures in butterflies and beetles: valuable sources for bioinspiration

In this review, a survey is presented of the development of natural photonic crystal‐type nanoarchitectures occurring in butterflies and beetles from the standpoint of physics and materials science, covering the past ten years.

Butterfly wing scales

Many organisms in nature have evolved sophisticated cellular mechanisms to produce photonic nanostructures and, in recent years, diverse crystalline symmetries have been identified and related to

The significance of the number of periods and period size in 2D photonic crystal waveguides

This work investigates the significance of the number of periods in two-dimensional photonic crystals. Models have been developed to study various photonic crystal properties (Reflection, Photonic

Highly Reproducible, Bio‐Based Slab Photonic Crystals Grown by Diatoms

Diatoms thereby offer a wide range of PhC structures, reproducible and equipped with well‐defined properties, possibly covering the entire UV‐vis–NIR spectral range.

Domain morphology, boundaries, and topological defects in biophotonic gyroid nanostructures of butterfly wing scales

The study of the scale structure reveals new aspects of photonic crystal growth in butterfly wings and shows their similarity to block copolymer materials, opening new avenues to exploration of fundamental processes underlying the growth of biological photonic nanostructures in a variety of species.



Diatoms as living photonic crystals

We present an analysis of the optical structure of a representative diatom, Coscinodiscus granii. The silica cell wall can be regarded as a photonic crystal slab waveguide with moderate

Animals have plenty to teach us, not only in terms of the design of their optical structures, but also their engineering, as biologists and physicists have begun collaborative optics–based projects where the data will be supplied by nature.

Gleaming and dull surface textures from photonic-crystal-type nanostructures in the butterfly Cyanophrys remus.

It is shown that the metallic blue dorsal coloration originates from scales which individually are photonic single crystals of 50 x 120 microm2 , while the matt pea-green coloration of the ventral side arises from the cumulative effect of randomly arranged, bright photonic crystallites with typical diameters in the 3-10-mum range.

Structure and development of iridescent butterfly scales: Lattices and laminae

In some iridescent scales, the reflective elements are contained within the body of the scale and come in two basic forms, lattices that produce diffraction colors (analogous to those produced by opal), and stacks of laminae that produce thin‐film interference colors ( analogous by soap or oil films).

Simulations reveal that the photonic-crystal structure possesses a partial photonic bandgap along the direction normal to the cortex surface, for frequencies within which light is strongly reflected.

Structural colour: Opal analogue discovered in a weevil

A beetle, Pachyrhynchus argus, found in forests in northeastern Queensland, Australia, is described that has a metallic coloration that is visible from any direction owing to a photonic crystal structure analogous to that of opal.

Optical properties of the iridescent organ of the comb-jellyfish Beroë cucumis (Ctenophora).

It is shown that the changing coloration which accompanies the beating of comb rows as the animal swims can be explained by the weakly-contrasted structure of the refractive index induced by the very coherent packing of locomotory cilia.

Structural origin of the colored reflections from the black-billed magpie feathers.

The structural origin of the weak iridescence on some of the dark feathers of the black-billed magpie, Pica pica (Corvidae), is found in the structure of the ribbon-shaped barbules. The cortex of
