12 months research engineer in physics and optoelectronics (M/F) – Project TranStab (LPL, USPN, Villetaneuse, France)

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

Postdoc or engineer position for LISA data preprocessing at SYRTE, Paris

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)

POST-DOC OFFER at FEMTO-ST– Besançon, France

Development of a stabilized laser on a sub-Kelvin Fabry-Perot cavity

Laboratory: FEMTO-ST– Besançon, France

Summary: Ultra-stable lasers have a central role in numerous scientific experiments for high precision measurements: atomic spectroscopy, diffusion of time & frequency signals by optical fiber, detection of gravitational waves and dark matter research. The performances are currently reaching fractional frequency stabilities below 10-16 at 1 second of integration. However, it is still insufficient for many applications including fundamental physics tests and optical atomic clocks. To overcome the current limits, the proposed offer consists in studying as finely as possible the behavior of a Fabry-Pérot cavity at 1 K, which will be used to stabilize a laser in frequency.

Offer details:

  • Prerequisites : PhD in Physics
  • Desired skills: Optical frequency metrology, Gaussian optics in free-space, Analog, digital and radio-frequency electronics, Control theory and locking/feedback techniques, Instrumentation, Cryogenic and ultra-high vacuum, Analysis and interpretation of noise and sources of noises
  • Contract duration : 1 year
  • Salary : approximately €2300 net
  • Procedure : Send CV, cover letter and at least 1 reference letter to jonathan.gillot@femto-st.fr.
