Post-doctorante ou Post-doctorant en transmission et détection sur fibres à cœurs creux – CDD de 18 mois

About This Opportunity

Our talent team is representing a confidential research institution in the Paris metropolitan area seeking a Postdoctoral Researcher specializing in transmission and detection on hollow-core optical fibers. This is an 18-month fixed-term contract focused on advancing next-generation photonic crystal fiber technologies for high-speed data transmission and sensing applications.

You will join a collaborative research environment working on hollow-core photonic crystal fibers (HCPCF), which have recently achieved propagation losses as low as 0.1 dB/km at 1550 nm. These fibers offer reduced latency (30-40% improvement), ultra-low dispersion, and negligible optical nonlinearities compared to standard telecommunications fibers, making them particularly promising for next-generation telecommunications systems, quantum key distribution, and distributed sensing applications.

Responsibilities

• Develop and demonstrate 400 Gbit/s transmission over several kilometers through novel hollow-core photonic crystal fiber architectures
• Investigate the potential of HCPCF technologies for sensing applications
• Perform numerical modeling and experimental characterization in the C-band
• Develop and implement digital signal processing (DSP) methods for polarization tracking to evaluate and optimize HCPCF transmission performance
• Collaborate iteratively between fiber fabrication and system-level characterization teams to ensure operational requirements are met
• Supervise and mentor interns and graduate students
• Contribute to research publications and participate in a multi-partner consortium focused on future optical networks

What We're Looking For

• PhD or equivalent in electrical engineering, communications, photonics, signal processing, or related field
• Strong knowledge of optical transmission systems and networks
• Solid background in digital signal processing (DSP) applied to communication systems or fiber-optic sensors
• Proficiency in MATLAB and/or Python for DSP algorithm development
• Strong interest in applied research and ability to work in a multicultural environment
• Excellent English language skills (essential for international collaboration)
• Strong interpersonal and pedagogical skills with demonstrated ability to synthesize and communicate complex technical information
• Team-oriented mindset with experience or willingness to supervise students
• Legal authorization to work in France for the contract duration
