Several biological organisms, from some sea shells to butterflies, exhibit sophisticated optical systems, which have been developed during the evolution of each species. The diatoms are microscopic algae enclosed between two valves of hydrated amorphous silica. These intricate structures, called frustules, show quite symmetric patterns of micrometric and nanometric pores. Their strong similarity with man-made objects suggests to exploit the optical properties of the frustules in light guiding and optical transducing. We have found very interesting results, both from the experimental and numerical points of view. (c) 2008 Elsevier Ltd. All rights reserved.
