Research Fellow - Integrated SNSPD Detectors

About the role

The National Centre for Advanced Integrated Photonics (NCAIP) at NTU is recruiting a Research Fellow to contribute to the development of integrated superconducting nanowire single-photon detector (SNSPD) technologies for on-chip quantum photonic and sensing platforms. The fellow works independently and in teams to deliver state-of-the-art single-photon imaging capabilities.

Key responsibilities

• Develop and experimentally validate waveguide-integrated SNSPD devices, including process integration, optical coupling optimization, efficiency measurement, timing-jitter characterization, photon-number-resolving operation and integration with quantum photonic circuits.
• Nanofabricate and develop integrated photonic and detector structures, including thin-film deposition, lithography, etching, process-flow optimization and materials/device characterization.
• Integrate SNSPDs into MWIR topological waveguides and detector platforms, and develop detector arrays and readout architectures, including multi-pixel arrays, multiplexed effective-pixel arrays, control/readout boards, hybrid cryogenic electronics and performance benchmarking.
• Support cryogenic packaging and system-level integration, including fiber-array coupling, electrical interconnects, compact chip packaging, low-noise readout interfaces and reliability/yield/stability assessment.
• Disseminate results through publications, reports and intellectual property contributions.

Required profile

• PhD in Physics, Photonics, Electrical Engineering, Materials Science, Nanotechnology or a related discipline.
• Strong research background in integrated photonics, nanophotonics, nanofabrication, photonic device fabrication, superconducting detectors or related fields.
• Proven publication record in reputable peer-reviewed journals.
• Experience in cleanroom fabrication and advanced materials/device characterization is preferred; familiarity with photonic waveguide platforms and detector integration is advantageous.
• Experience with SNSPDs, superconducting materials, cryogenic measurements, MWIR photonics, detector arrays, readout electronics or cryogenic packaging is an added advantage.

Required skills

• Scientific programming, data analysis, simulation and modeling tools such as Python, MATLAB and TCAD, and photonic simulation software.
• Analytical, problem-solving, communication and teamwork skills, with the ability to work independently in a research environment.
