Job description

The Research Fellow at NTU’s National Centre for Advanced Integrated Photonics (NCAIP) will support the development of integrated polaritonic devices and waveguides, focusing on long-range polariton propagation, low-energy switching, few-particle modulation of condensate nonlinearities, integrated polaritonic circuit functions, and coupling of polaritonic states with on-chip detection and readout architectures. The role will involve advanced optical spectroscopy and characterization techniques, including real-space and Fourier-space imaging, polarization- and time-resolved measurements, room-temperature and cryogenic testing, while working closely with device integration teams to advance integrated polaritonic systems.

Key Responsibilities:

• Design, fabricate, assemble, optimize and experimentally characterize integrated polaritonic devices and waveguides.

• Develop and operate optical spectroscopy setups involving real-space/Fourier-space imaging, polarization-resolved spectroscopy, time-resolved photoluminescence, electroluminescence, and room-temperature and/or cryogenic measurements.

• Investigate low-power and few-particle polaritonic effects, including condensate nonlinearities, low-energy switching, single- or few-polariton emission regimes, photon-correlation behaviour, and routes toward polaritonic logic or routing functions.

• Develop long-range polaritonic waveguiding platforms, polariton propagation measurements, electrical or optical routing schemes, and integration of polaritonic waveguides with single-photon detection where relevant.

• Collaborate with photonic device integration teams and CDPT partners to support device fabrication, assembly, testing and prototype demonstration.

• Operate and maintain research laboratories, including advanced microscopy and spectroscopy equipment, in compliance with safety and laboratory protocols.

• Perform data analysis and interpretation, prepare scientific publications, contribute to research reports and IP disclosures, and present findings at international conferences.

• Collaborate with internal and external partners on joint research projects and technology development.

• Contribute to progress reports, project meetings, day-to-day laboratory operations, future grant proposals, and the development and protection of intellectual property.

Requirements:

• PhD in Physics, Optical/Photonic Engineering, Materials Science, Electrical Engineering, or a related discipline.

• Relevant research experience in experimental optics, optical spectroscopy, photonics, exciton-polariton physics, nonlinear optics, semiconductor optics, polaritonic waveguides, or related fields.

• Proven publication record in reputable international peer-reviewed journals.

• Hands-on experience in optical system design, alignment, operation, and advanced characterization techniques, including laser-based and imaging setups.

• Competent in scientific programming and data analysis (e.g., Python/Matlab), with strong communication skills and the ability to work independently and collaboratively within a research environment.
