Job description

The Research Fellow at National Centre for Advanced Integrated Photonics (NCAIP) will contribute to the development of integrated superconducting nanowire single-photon detector (SNSPD) technologies for on-chip quantum photonic and sensing platforms.

Key Responsibilities

As an integral part of the project, the Research Fellow is expected to conduct research in integrated SNSPD detectors and readout technologies, including the development and experimental validation of waveguide-integrated SNSPD devices; process integration; optical coupling optimization; on‑chip detection‑efficiency measurement; timing‑jitter characterization; photon‑number‑resolving operation; and detector integration with quantum photonic circuits. The role also includes nanofabrication and process development for integrated photonic and detector structures, including thin‑film deposition, lithography, etching, wafer‑or‑chip‑scale process flow optimization, and materials/device characterization. The Research Fellow will also develop SNSPD integration in MWIR topological waveguides and waveguide‑integrated MWIR detector platforms, including device fabrication/assembly, coupling to MWIR waveguides, and optimization of detector performance. The role further includes development of SNSPD detector arrays and readout architectures, including multi-pixel detector arrays, space-or-time-multiplexed effective-pixel arrays, photon-number-resolving detection, integrated electronic boards for control/readout, hybrid cryogenic electronics, biasing, amplification, thresholding, digitization, and detector-array performance benchmarking. The Research Fellow is expected to support cryogenic packaging and system-level integration, including fiber-array coupling, electrical interconnects, compact packaging of detector chips, low-noise readout interfaces, and reliability/yield/stability assessment of integrated detector prototypes. The Research Fellow is expected to work, generate ideas and experimentally prove them both independently and within team-working efforts with other researchers working on the project to deliver state‑of‑the‑art single‑photon imaging capabilities, and to disseminate results through publications, reports, and IP contributions.

Requirements

• 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 processes and advanced materials/device characterization techniques is preferred.
• Familiarity with photonic waveguide platforms and detector integration technologies is advantageous.
• Experience with SNSPDs, superconducting materials, cryogenic measurements, MWIR photonics, detector arrays, readout electronics, or cryogenic packaging will be an added advantage.
• Proficiency in scientific programming, data analysis, simulation, and modeling tools (e.g., Python, MATLAB, TCAD, photonic simulation software).
• Strong analytical, problem-solving, communication, and teamwork skills, with the ability to work independently in a research environment.
