Offer Description

This project will be carried out through a collaboration between CRHEA, which will be the candidate's main workplace, LPL in Villetaneuse, and MPQ in Paris. The collaborating laboratories provide access to electromagnetic simulation tools, cleanroom facilities, and optical characterization setups required for the design, fabrication, and characterization of the metasurfaces and OLED devices.
This multidisciplinary environment will allow the PhD candidate to work at the interface between nanophotonics, metasurfaces, organic optoelectronics, nanofabrication, and advanced optical characterization.
The PhD candidate will be involved in the design, fabrication, and characterization of metasurfaces and optical sources, as well as in the investigation of their optical properties and their integration.
Previous experience in all the topics and techniques involved in the project is not required. However, the candidate should be highly motivated to develop expertise across these different areas. A strong background in photonics is expected, and previous knowledge of metasurfaces, nanophotonics, optical sources, electromagnetic simulations, or optical characterization would be particularly appreciated.
The candidate should demonstrate good organizational skills, scientific curiosity, autonomy, and the ability to work effectively within a collaborative and multidisciplinary research environment.
Applicants should hold a Master's degree or equivalent qualification in physics, preferably with a specialization in photonics, optics, or nanophotonics.

The project will combine electromagnetic modelling, metasurface design, nanofabrication, and optical characterization. The work will include the modelling of the interaction between emitters and nanophotonic structures, the investigation of dispersion diagrams and resonant modes, and the optimization of the structures to simultaneously maximize emission directivity and light extraction efficiency.
The selected architectures will then be fabricated using the micro- and nanofabrication facilities available at CRHEA. Their optical properties will be investigated using spectral and angle-resolved measurements, enabling the reconstruction of emission patterns in reciprocal space and a quantitative assessment of the achieved control over light emission.
The fabricated structures will subsequently be combined with organic emitters to investigate their emission directivity under optical excitation. This intermediate step will provide a detailed understanding of the coupling between the organic emitters and the photonic modes supported by the metasurface before the fabrication of complete OLED devices.
Finally, the design and integration of wavefront-shaping functionalities will aim at demonstrating a first prototype of a directional meta-OLED capable of generating structured light. The organic materials and OLED devices will be fabricated at LPL.
