Two-dimensional photonic crystals (PhCs) in waveguide geometry are a recent concept for light propagation control, which has seen its main promises verified in the optical range. They have the potential to be the building block of a novel generation of optical circuits combining high-speed processing and very high scale integration. However, for the control of light emission, these 2D PhC suffer from a lack of confinement in the third (vertical) dimension. In this context, three-dimensional issue of nanostructuring, thanks to their bottom-up approach.The purpose of the present experimental and theoretical proposal is to benefit from the versatility and manufacturability of silicon to realize hybrid architectures combining 2D planar PhCs and self-assembled 3D PhCs.The goal is to provide conceptual tools to design advanced photonics architectures combining integrated light sources and routing functions for telecommunications wavelengths. The basic issues addressed will be spontaneous emission control in 3D PhCs, routing functions in 2D PhCs, electrical addressing of PhCs, and coupling between 2D and 3D PhC in hybrid architectures. The present project will address many of the main targets of the thematic priority In-formation Society Technologies, such as the access to all part of the society to the information, by mean of user-friendly and secured services.
