Overview

This doctoral position focuses on the design, fabrication monitoring, and laboratory characterization of multiplexed photon sources using silicon photonics. Based at the Photonics Integration Laboratory on Silicon (LETI) in France, the research aims to overcome single-source limitations by implementing efficient on-chip photon generation and integrated filtering. The selected candidate will work closely with research staff to advance scalable optical devices operating at room temperature for quantum technologies. Expected duties include experimental testing, data analysis, and contributing to project documentation and scientific publications.
