Senior Scientist, TFLN-on-Silicon Photonics Modulators

A*STAR - Agency for Science, Technology and Research; Singapore; On-site; SGD 120,000 - 190,000; Full time

Job summary

A*STAR - Agency for Science, Technology and Research in Singapore seeks a Senior Scientist in the Silicon Photonics Department to drive heterogeneously integrated PICs using thin-film lithium niobate on silicon. You will lead device concepts, collaborate across design, process integration and packaging, and push manufacturable solutions with industry partners and research collaborators.

This role requires a PhD and a strong background in photonics, with proven leadership and project execution

Qualifications

• PhD in Electrical Engineering, Physics, Materials Science, Photonics, Semiconductor Engineering, or a related discipline.
• Strong background in semiconductor device design, fabrication, or process integration.
• Experience in TFLN photonics and silicon photonics is highly desirable.
• Excellent communication, presentation and project management skills.
• Ability to work independently while collaborating within multidisciplinary teams.

Responsibilities

• Lead the development and implementation of novel device concepts for the heterogeneous integration of lithium niobate (LN) on 200 mm and 300 mm silicon‑on‑insulator (SOI) platforms.
• Develop product‑ready TFLN‑on‑Silicon Photonics (SiPh) modulators targeting 400 Gbps‑per‑lane and beyond optical interconnect applications.
• Collaborate closely with photonics integration and process development teams to realize the co‑integration of TFLN modulators and germanium (Ge) photodetectors on a common silicon photonics platform.
• Analyze and correlate in‑line process data and off‑line characterization results to understand the impact of process variations on device performance and yield.
• Drive device optimization, process integration, and technology maturation toward manufacturable solutions.
• Manage and execute R&D projects efficiently, accelerating development cycles while delivering value to internal and external stakeholders.
• Engage with industry partners, foundry ecosystems, and research collaborators to advance heterogeneous photonic integration technologies.
