## Description

Join Quandela's Source Production team to work on the fiber pigtailing of single-photon sources.
The role focuses on developing, improving and operating highly precise fiber coupling methods for photonic quantum devices.

The role is part of the Source Production team, which currently includes 11 people across fabrication, fiber pigtailing and optical characterization. The role is part of the pigtail team, currently composed of one person, and works in close interaction with the fabrication and characterization teams.

The objective is to improve the reliability, reproducibility and productivity of the pigtailing process, from prototype development to production-ready methods.

Key responsibilities

 * Integrating mircro-structure to the PIC waveguide edge coupling

 * Perform high-precision fiber coupling between single-mode fibers and individual micropillars, with alignment precision below 100 nm
 * Develop and improve methods to evaluate coupling and alignment quality through clear metrics
 * Cool down pigtailed sources and support the validation of the assembled devices
 * Perform optical characterization of quantum emitters using quantum optics techniques, including single-photon detection
 * Contribute to the development of reliable and reproducible production procedures
 * Write systematic reports and share production feedback with other teams
 * Work closely with the fabrication and optical characterization teams
 * Contribute to productivity improvements and risk mitigation in the pigtailing process
 * Simulation experience is a plus
