Unlike most natural colours that are based on pigment absorption,
the striking iridescent and intense colouration of many
butterflies, birds or beetles stems from the interaction of light
with periodic sub-micrometer surface or volume patterns, so called
"photonic structures". These "structural colours" are increasingly
well understood, but they are difficult to create artificially and
exploit technologically. In this thesis the field of natural
structural colours and biomimetic photonic structures is covered in
a wide scope, ranging from plant photonics to theoretical optics.
It demonstrates diffractive elements on the petal surfaces of many
flowering plant species; these form the basis for the study of the
role of structural colours in pollinator attraction. Self-assembly
techniques, combined with scale able nanofabrication methods, were
used to create complex artificial photonic structures inspired by
those found in nature. In particular, the colour effect of a
Papilio butterfly was mimicked and, by variation of its design
motive, enhanced. All photonic effects described here are
underpinned by state-of-the-art model calculations.
