Biomimetic and bio-inspired attempts to produce novel photonic structures have attracted increasing research interest in recent years. Nature offers an enormous amount of multifunctional micro- and nanostructures that provide outstanding, distinctive, dynamic and tailored coloration and high reflectivity. Various intriguing photonic structures have been identified on the wing scales of beetles, butterflies, the feathers of birds or in marine animals. Nature offers a huge reservoir of blue-prints for novel artificial optical materials and photonic structures. We present the development of bio-inspired, dynamic, micro-optical elements that are comparable to some of natures efficient optical systems. Artificially controlled self-assembly combined with established nanofabrication techniques can be used for the development of new optically-adaptive devices. Novel optical elements have to address the aspect of tunability and multifunctionality to be versatile for a wide range of applications. Furthermore, we propose a technique to create fully organic adaptive optical systems based on elastic multilayer micro-rolls.
