Photonic structures in ordered, quasi-ordered or disordered forms have evolved across
many different animal and plant systems. They can produce complex and often functional …

The most vibrant and striking colours in living organisms are often caused by a combination
of pigments and nano-scale transparent architectures, which interact with light to produce so …

The scales of Morpho butterflies are covered with intricate, hierarchical ridge structures that
produce a bright, blue reflection that remains stable across wide viewing angles. This effect …

Additive manufacturing has recently seen drastic improvements in resolution, making it now
possible to fabricate features at scales of hundreds or even dozens of nanometers, which …

Iridescent structural colors in biology exhibit sophisticated spatially-varying reflectance
properties that depend on both the illumination and viewing angles. The classification of …

The brilliant blue coloration of the Morpho rhetenor butterfly originates from complex
nanostructures found on the surface of its wings. The Morpho butterfly exhibits strong short …

Many plant surfaces, such as rose petals, display lens-like epidermal cells that are known to
assist the collection and focusing of the sunlight. Those cells form an array with a high …

Structural coloration produces some of the most brilliant colors in nature and has many
applications. Motivated by the recently proposed transparent displays that are based on …

We present an approach for designing nanostructured surfaces with prescribed visual
appearances, starting at design analysis and ending with a fabricated sample. The method …

We show that disorder-induced interaction between guided modes and a flat band of low-Q
radiating modes in planar arrays of dielectric particles can lead to frequency-selective omni …
