Postdoc: Metasurfaces for Optical ELMs in Multicore Fibers

CNRS - National Center for Scientific Research; France; On-site; EUR 28,000 - 42,000; Full time

Job summary

CNRS – National Center for Scientific Research, Metasurface Team at CRHEA, seeks a postdoctoral researcher for six months to advance optical metasurfaces for lensless endoscopy and photonic computing within the ANR MetaCoupler project.

The role focuses on implementing passive metasurfaces to realize trained weights, exploring PB and ERI phase architectures, and fabricating/characterizing a demonstrator on the PhLAM ELM test bench.

Qualifications

• PhD in physics, optics, photonics, electrical engineering or closely related field.
• Experience in nanophotonics and metasurfaces is essential.
• Experience with electromagnetic simulations and scientific programming is required.

Responsibilities

• Design and optimize passive dielectric metasurfaces with complex optical weights.
• Investigate ERI and Pancharatnam-Berry phase architectures for polarization and efficiency.
• Translate numerically trained weights into manufacturable optical masks and assess quantization and fabrication tolerances.
• Fabricate and characterize passive metasurface demonstrators and support integration on the PhLAM ELM bench.
• Collaborate with PhLAM partners and cleanroom staff throughout the project.
