Description

Scientist / Senior Scientist – High-Speed TFLN Modulators & Photonic Heterogeneous Integration (PHI)

As part of IME’s Silicon Photonics Department, the successful candidate will play a key role in developing next-generation high-speed optical modulators based on Thin-Film Lithium Niobate (TFLN) and Photonic Heterogeneous Integration (PHI) technologies. The work focuses on advancing TFLN-on-Silicon Photonics (SiPh) platforms for AI, data center, and next-generation optical interconnect applications beyond 400 Gbps per lane.

The candidate will collaborate with multidisciplinary teams spanning photonic device design, process integration, wafer fabrication, packaging, and testing, leveraging IME’s state-of-the-art 200 mm and 300 mm manufacturing facilities to develop scalable, manufacturing-ready photonic technologies.

 Responsibilities

• Design, develop, and optimize high-speed TFLN and TFLN-on-SiPh electro-optic modulators.
• Develop product-ready modulators targeting 400 Gbps-per-lane and beyond for next-generation optical interconnects.
• Collaborate with process integration teams to realize heterogeneous integration of TFLN, silicon photonics, and germanium photodetector technologies.
• Develop advanced RF-photonic co-design methodologies, travelling-wave electrodes, and high-speed device architectures.
• Analyze device performance, process variations, and characterization data to drive yield and performance optimization.
• Contribute to platform development, PDK enablement, and technology transfer activities.
• Work with industry partners and research collaborators to advance PHI technologies and applications.
