The work presented in this thesis deals with the study of the photonic properties of four diatom species of the genus Coscinodiscus: C. wailesii, C. specie, C. radiatus et C. radiatus-cf. Diatoms are unicellular microalgae consisting of a single cell encapsulated in an inorganic matrix of porous silica called frustule. We performed cultures of these species, then extracted the frustules to characterize them, both in terms of their composition and their morphology, by electron microscopy and X-ray tomography. The frustule consists of three silica layers (the foramen, cribrum and cribellum) with a hierarchical porous structure, ranging from micrometer to nanometer scale, and thus forming a complex three-dimensional matrix that may have photon...
