Résumé du poste

Quandela is seeking a PhD-level scientist to join the Source Production team for optical characterization of single-photon sources in optical cavities. You will measure, optimize, and validate emitter performance, improving reliability and reproducibility of procedures.

The role involves daily bench work on cryogenic setups and collaboration with fabrication, pigtailing and production teams, with opportunities to automate data processing in Python.

Qualifications

• PhD in optics, photonics, quantum optics or experimental physics.
• Ideal seniority: fresh PhD to around 2 years of experience after PhD.
• Strong hands-on experience with optical characterization setups.
• Experience with quantum dot spectroscopy or single-photon source characterization.
• Experience with cryogenic setups and vacuum components.
• Python skills for instrumentation control and data processing.

Responsabilités

• Perform optical characterization of single-photon sources in optical cavities.
• Use standard excitation schemes such as LA, RF, SUPER and related techniques.
• Perform quantum dot spectroscopy and analyze emitter properties.
• Optimize pulse shaping and laser filtering to improve single-photon emission quality.
• Measure key performance indicators: lifetime, indistinguishability, brightness, purity, spin properties.
• Automate instrumentation, data acquisition and processing using Python.
• Collaborate with fabrication, pigtailing and production teams.
