The ILUM/Mid-IR team at INL is conducting research in the field of integrated nonlinear optics in the mid-infrared (Mid-IR wavelength range between 3 and 13 um) in strong interaction with its partners from the OFCOC (Optical Frequency Comb On a Chip) consortiumof the PEPR e- including CEA-LETI, FOTON, C2N, IES and international partners from the LIA ALPhFA (ANU, RMIT, Swinburne) and supported by several European projects (ECLAUSion, AUFRANDE, MicroCOMBSys) and ANR projects (MIRSiCOMB. MIRthFUL, OFCOC..).
This consortium is pionner in this field with several seminal demonstrations at the frontier of fundamental/applicative research. One of the strong axes of this activity is the development of miniaturized, intense, broadband sources (for sensor applications (industrial monitoring, pollutants, greenhouse gas, health, security...).


The postdoctoral researcher will work under the supervision of Christian Grillet and Prof. Christelle Monat in the iLUM team at the Institut des Nanotechnologies de Lyon (INL- UMR 5270) as part of the PEPR e- OFCOC (Optical Frequency Comb On a Chip) project.
He/she will contribute to the development of integrated nonlinear functions such as combs and mid-infrared supercontinuum sources on Ge/SiGe and SiN platforms (in collaboration with CEA-LETI), GaP (in collaboration with FOTON and C2N).
He/she will be involved in all stages of the project, from the design of the devices using commercial electromagnetic modeling tools (MODE or FDTD from LUMERICAL, RSOFT...) or developed in-house (NLSE, LLE...) to the manufacture of the devices using cleanroom processes via the NANOLYON nanotechnology platform (nanolithography, etching) and their optical characterizations. The postdoctoral researcher will work in close collaboration with our collaborators at CEA-LETI, FOTON and C2N for nonlinear aspects, and with IES Montpellier for integration aspects (by microtransfer printing) of ICL lasers on GaP or SiGe (in close collaboration with several members of the iLUM team - Xavier Letartre, Christian Seassal - and the NanoLyon platform - Céline Chevalier, Jean-Louis Leclerc.
He/she will be responsible for the scientific and technical supervision of several PhD students (French and international).


The recruited candidate, who holds a PhD, must have solid experience (theoretical and experimental) in nonlinear optics, parametric processes (FWM, supercontinuum, combs...) integrated optics and short pulse lasers. He/she will have strong programming/modeling skills (SSFM, LLE, Matlab, Python...) and the ability to set up a Mid-IR optical bench. Experience in at least one of the following fields would also be highly appreciated:
- Microtransfer printing (i.e. III-V source on Si...)
- Cleanroom manufacturing, material deposition, etc.
- Spectroscopy/metrology

The candidate must have a strong taste for teamwork, show initiative and be a driving force in coordinating the national and international collaborative efforts.
He/she has or will be able to develop the ability to supervise PhD students.
He/She has very good written and oral skills (English at least for writing articles, grants and presenting results to international conferences).

Contexte de travail

Awarded the Nobel Prize in Physics in 2005, work on optical frequency combs has revolutionized the field of optics, with the development of high-resolution spectroscopy in the fields of health, the environment, security and information technology. However, frequency combs are still limited to niche applications, as they are difficult to implement. Very recently, the first demonstrations of frequency combs on chip (microcombs) have opened the way to the volume use of these frequency combs.
In the PEPR electronics OFCOC (Optical Frequency Combs On a Chip) project, we propose to build the first integrated, broadband (visible to mid-infrared), robust, reliable and miniaturized microcomb source on an all-semiconductor platform. To achieve this, we will be working on the co-integration of two French fields of excellence: antimony-based ICLs (interband cascade lasers) and the GaP non-linear platform, to guarantee France a strategic position in this competitive sector. These two technologies are the best placed in the world to provide integrated optical pumping of frequency combs and ultra-wideband frequency conversion. The growth of these two sectors will be supported by state-of-the-art technologies (SiGe and SiNOI) for the generation state-of-the-art technologies (SiGe and SiNOI) for frequency comb generation in MIR and NIR.

Le poste se situe dans un secteur relevant de la protection du potentiel scientifique et technique (PPST), et nécessite donc, conformément à la réglementation, que votre arrivée soit autorisée par l'autorité compétente du MESR.

Contraintes et risques

Short trips in France (to our PEPR collaborators) and abroad (Australia) are to be expected.
