Research Fellow (Integrated Photonics)

National University of Singapore, Singapore

Updated: 5 days ago

We are currently accepting applications for a Postdoctoral Research Fellow to contribute to research in integrated photonics, heterogeneous photonic integration, and high-speed electro-optic devices. The successful candidate will develop high-performance photonic devices based on lithium niobate, silicon photonics, and heterogeneous material platforms, with emphasis on electro-optic modulators, low-loss photonic components, and scalable integration technologies.
The candidate will participate in the design, fabrication, integration, and characterization of lithium niobate and LN-on-Si photonic devices, and explore advanced integration approaches such as micro-transfer printing for back-end-of-line compatible photonic integration for next-generation optical interconnects and electronic-photonic systems.

Key Responsibilities:

•    Design and develop high-performance integrated photonic and electro-optic devices based on lithium niobate, silicon photonics, and heterogeneous platforms.
•    Develop fabrication and heterogeneous integration processes for lithium niobate and silicon photonic devices, including micro-/nanofabrication and micro-transfer printing.
•    Conduct optical, electro-optic, and high-speed characterization, including transmission spectra, propagation loss, modulation efficiency, electro-optic bandwidth, S-parameters, and high-speed modulation measurements.
•    Perform photonic device simulation and optimization using tools such as Lumerical FDTD, or equivalent simulation platforms.
•    Analyze device physics and process–performance relationships, collaborate with multidisciplinary research teams, and publish research results in high-impact journals and leading international conferences.
