Metasurfaces offer complete control of optical wavefront, such as phase, amplitude and polarization at the subwavelength scale, enabling a new class of artificial two-dimensional optics. Metasurfaces hold great potential in on-chip optoelectronic integration applications, which will significantly promote the development of miniaturized optoelectronic systems. In this presentation, i will review our group results on Metasurfaces integration in VCSEL and new results on vectorial holography and LiDARs.

The evolution of spectro-polarimetric properties of metasurfaces made of plasmonic U-shaped resonators is investigated upon absorption of antimicrobial peptides. The sensitivity of the metasurfaces to refractive modifications is shown to depend on the incident polarization at a given wavelength in relation with the resonant modes excited in the resonators. The metasurface allowed for monitoring the time dependence of the absorption of thiol-functionalized peptides at the surface of the resonators.

The use of nanostructures in photovoltaic cells is seen as an interesting strategy to improve their performances. Well designed nanotextures can indeed lead to a better coupling of light into the solar cell by reducing reflection losses or by enhancing the light-absorption in the semi-conductor material. Here, we focus on perovskite single-junction solar cells and we use numerical modeling to study the impact of different types of periodic nanostructures (nanopillars, inverted pyramids or sinusoidal nanostructures) on their optical response.

Periodic arrays of nanoparticles have emerged as ideal platforms to achieve numerous applications, from ultrasensitive optical sensing to nanolasing, thanks to their ability to support collective responses known as lattice resonances. These modes, which emerge at wavelengths commensurate with the array periodicity, are characterized by strong and spectrally narrow optical responses. Here, we report on the lattice resonances supported by complex arrays containing multiple nanoparticles per unit cell. The additional degrees of freedom in these systems enable much richer coupling scenarios that hold promise for a diverse range of applications.
The impact of Rayleigh anomalies on the emission pattern of organic emitters

We report the investigation of Ag-nanoparticles grating with various periods on the emission pattern of organic molecules. Our results show that the presence of Rayleigh anomalies strongly modifies the spectral responses of the gratings, and offers a mean to control the spatial properties of organic emitters in the far field. Moreover, they show that these features are at the origin of the collective lattice responses as they impose the excitation condition for which the nanoparticles can act as a set of diffractive objects to shape the emission to be highly directive.
