Abstract: A method of manufacturing a three dimensional photonic device by two photon absorption polymerization. The method includes several stages, including direct laser writing involving polymerization by two-photon absorption to manufacture a three dimensional photonic device integrating at least two distinct micro-optical components having two optical functions and being aligned with each other so that optical signal can be transmitted from one of said distinct components to the other. The distinct components are built at a same stage of the process flow to improve their relative alignment by direct laser writing involving polymerization by two-photon absorption.
