Scientist, Photonics (Integrated Quantum Light Sources, TFLN), A*STAR Quantum Innovation Centre, Singapore

Job Description

A*STAR’s Quantum Innovation Centre (Q.InC) is hiring a Research Scientist in photonics to develop integrated quantum light sources for photonic quantum processors. The focus is wafer-scale poling and advanced characterisation of thin-film lithium niobate (TFLN), a leading platform for on-chip sources of entangled and squeezed light. Much of the job is automation: building control, data-acquisition and screening systems so that large numbers of devices can be tested quickly and fed back to the fabrication team.

At a glance

• Posted: 8 May 2026 (Req ID 2290)
• Apply: open until filled (re-checked 14 October 2026)

Responsibilities

• Build automated control and data-acquisition systems for poling, confocal domain imaging and fibre-to-chip coupling measurements
• Set up high-throughput wafer-scale screening of poling quality, optical loss and coupling efficiency
• Integrate optical, electrical and mechanical instruments into a robust automation framework
• Optimise measurement speed, reproducibility and scalability
• Turn fabrication variability into testing and feedback strategies that improve yield, working with the fabrication team
• Mentor junior researchers and students

What A*STAR is looking for
