Missions

To develop effective metasurfaces devices in the mid-infrared to control the properties of light (polarization, intensity, phase profile of the light wavefront). This project will be able to draw on the skills acquired during the Doctorate and by working in close collaboration with the members of the metasurfaces team at CRHEA.

Activities

The candidate will have to address the issue of extending nanostructuring technology to the mid-infrared spectral range. He / she will develop metasurfaces with non-absorbent dielectric materials such as GaSb, so as to improve wavefront control properties for imaging applications.

Skills

Metasurfaces, digital models, nanotechnologies. Development of new optical devices for wavefront control.

Work Context

The Research Center for Hetero-Epitaxis and its Applications (CRHEA) is a CNRS research laboratory specializing in the epitaxy of high bandgap semiconductor materials such as element III nitride materials (GaN, AlN) , zinc oxide (ZnO), silicon carbide (SiC) and their micro- and nanofabrication in clean rooms. CRHEA is also studying 2D materials such as graphene or boron nitride.
The main areas covered by CRHEA concern energy transition, future communications, the environment and health. CRHEA also carries out fundamental studies in nanoscience and crystal growth.
High bandgap energy materials are key elements for power electronics, very high frequency electronics, LED-based lighting and new generations of micro-displays. The laser sources operating in the visible and in the Ultra-Violet produced at CRHEA have multiple applications for lighting, biophotonics and for water purification. CRHEA also develops components in the THz field, photonic circuits, advanced optical components based on metasurfaces, applications in spintronics, sensors and is involved in the development of quantum technologies.
The laboratory has eight molecular beam epitaxy growth reactors and six vapor phase growth reactors. It also has tools for the structural characterization of materials and a clean room for micro and nanofabrication.
Context of the integration team:
The combination of top-down and bottom-up approaches makes it possible to exploit all the possibilities offered by nanostructures and this is the strength of the Nanotechnologies team, which uses GaN and ZnO as materials of choice. Our interests range from basic materials science, including the MBE and MOCVD growth of new materials (eg ZnMnO, rare earth nitrides and oxynitrides), to the development of more complex nanophotonic systems. These are in particular metasurfaces, which allow the manufacture of ultrathin-ultralight optoelectronic components such as metal lenses, optical microcavities.
The latter are the ideal playground for testing effects in quantum electrodynamics and obtaining Bose-Einstein condensates in a semiconductor environment. Finally, a latest nanophotonic platform based on GaN nanowires is capable of stimulating biological cells with unprecedented spatial resolution. Moreover, the manipulation of the spin of carriers and / or excitons within these photonic structures, thanks to our magnetic materials, opens up the possibility of coupling spin and photons in an electrically addressable interface.
