Nature's color has three main sources: pigments, structural colors and bioluminescence.
Structural color is a special one, which is the color produced by micro-or nano-structures …

Photonic crystal fibers present a wavelength-scale periodic microstructure running along
their length. Their core and two-dimensional photonic crystal might be based on varied …

Nature began develo** photonic nanoarchitectures millions of years before humankind.
Often, in the living world, color is a communication channel that may influence the chance of …

Morpho butterfly, famous for its iridescence wing scales, has gradually evolved a diversity of
functions and has attracted much attention recently. On the other hand, it is known that the …

The ability to control light at the nanoscale is at the basis of contemporary photonics and
plasmonics. In particular, properly engineered periodic nanostructures not only allow the …

The origin of the structural colors from several different examples of the weevil and longhorn
families (Curculionidae and Cerambycidae, respectively) was investigated by structural and …

The photonic nanoarchitectures responsible for the blue colour of the males of nine
polyommatine butterfly species living in the same site were investigated structurally by …

The iridescent structural colours of butterflies, generated by photonic nanoarchitectures,
often function as species-specific sexual signals; therefore, they are reproduced precisely …

Photonic structures incorporated in lepidopteran scales are responsible for a very broad
range of optical effects: iridescence, narrow-band reflection, large solid-angle scattering …

We report the investigation of a nano-scale antireflection structure in the black scales of the
Troides aeacus butterfly wing, which can be viewed as a natural solar collector. The …
