This work reports for the first time theoretical third order nonlinear optical susceptibilities of YSH bulk phases which are key properties for telecommunication technologies and integrated photonic devices. Our outcomes, relying on coupled perturbed Kohn-Sham density functional theory expose that the NLO capacity of YSH should be similar to anothe...
We present a photonically-excited antenna array at E-band for scanning by beam switching in wireless links. First, we discuss the proposed technique applied to photonic-enabled (sub)millimeter-wave transmitters. Next, we present the proposed solution; it consists of two sub-arrays of stacked patches as primary feeds of a Polytetrafluoroethylene (PT...
As we transition towards a more sustainable society, high-performance bio-based materials are increasingly required. In this context, cellulosic materials hold exceptional promise as they are derived from abundant and bio-sourced feedstock, and they are able to self-assemble into nanoscale architectures. More specifically, several cellulose derivat...
Nowadays, communication networks are becoming more and more important, with the massive emergence of social networks, "streaming" platforms, or even the "Internet of things" for example. In this context where the demand in terms of communications continues to grow, it is necessary to find new technological solutions to overcome the limitations pose...

Much of the progress in astronomy has been driven by instrumental developments, from the first telescopes to fiber fed spectrographs. In this review, we describe the field of astrophotonics, a combination of photonics and astronomical instrumentation that is gaining importance in the development of current and future instrumentation. We begin with ...
