12-month Post-Doc contract at FEMTO-ST – Time and Frequency Department – Besançon, France

Researc Topic: Development of an ion trapping chip for time and frequency metrology

=> More details

The candidate will be part of the Embedded Metrology team of the Metrology, Molecule and Fundamental Tests axis of the Laser Physics Laboratory (UMR7538). He/She will work under the supervision of Vincent Roncin (MCF, HDR) and Frédéric Du-Burck (Pr Emerite) as part of the BRIOCHE project (ANR ASTRID 2024-2027 funding), the aim of which is to study, produce and characterize a transportable 1.5 µm frequency reference for on-board metrology instrumentation applications.

The candidate will be responsible for managing the project and organizing all the experimental studies involved:

1. Progress on two prototypes of transportable metrological references produced in collaboration with
   project partner Silentsys,
2. Improvement of noise rejection techniques for the detection of weak signals in Acetylene
   spectroscopy,
3. Study of an original technique for detecting saturated absorption signals in interference-insensitive
   fibered devices.

Closing date for the receipt of applications: 30/10/2024

The TranStab project (supported by ANR) brings together two academic laboratories (LPL/CNRS-USPN and Institut FOTON/CNRS-UR) and an industrial company (Thales TRT) over a three-year period to design and demonstrate compact devices for transferring stability from an optical frequency reference at 1.5 µm to wavelengths of interest ranging from the near IR to the visible. The aim is to meet the growing need for stable laser sources in both research and industry for applications in high-sensitivity detection and quantum technologies.

The candidate will be part of the Embedded Metrology team of the Metrology, Molecule and Fundamental Tests division of the Laser Physics Laboratory (UMR7538). He/she will work under the supervision of Vincent Roncin (MCF, HDR) and Frédéric Du-Burck (Pr Emeritus) as part of the TranStab project (ANR 2024-2027 funding).

The candidate will be responsible for monitoring the project and organizing all experimental developments:

1. Production of prototype cavities using the two architectures described above,
2. Characterization of their metrological performance.

Closing date for the receipt of applications: 15/01/2025

The LISA (Laser Interferometer Space Antenna) space mission will allow the detection of low frequency gravitational waves. In this project, we will develop new methods to reduce various noises in the LISA data efficiently in order to detect gravitational waves and to extract scientific results for various types of sources. This position is devoted either to a researcher or to a software engineer. Strong skills in software development, data analysis, and numerical calculations are required. In addition, knowledge of the LISA mission and of its instruments will be favoured. This project will be conducted within the “Theory and metrology” group at SYRTE.

Starting date: November 1, 2024

Duration: 1 year (can be extended to 2 years or more)
