Research Fellow - Waveguide-Integrated SNSPDs

About the role

Nanyang Technological University (NTU) in Singapore is recruiting a Research Fellow / Research Engineer (Project Leader) at its Centre for Disruptive Photonic Technologies (CDPT) and National Centre for Advanced Integrated Photonics (NCAIP). The role integrates Superconducting Nanowire Single-Photon Detectors (SNSPDs) with advanced quantum photonic integrated circuits (PICs) and scales up fabrication, testing and packaging workflows toward a commercially viable single-photon detection prototype.

Key responsibilities

• Design PIC components and integrate SNSPDs with photonic integrated circuits.
• Scale and optimize fabrication and cryogenic testing workflows.
• Characterize detector and system performance, including detection efficiency, dark count rate, timing jitter and yield.
• Develop packaging solutions compatible with the cryogenic environment and manage and document process, design and measurement data.
• Operate and maintain research laboratories, including cryostats and optical setups, in line with safety and laboratory protocols.
• Take part in the Venture Creation Program and pilot tests with research groups and industry partners, and explore use cases for the prototype.
• Contribute to progress reports, IP disclosures and grant proposals, and share results through publications and international conferences.

Required profile

• Ph.D. or doctorate in Physics, Optical/Photonic Engineering, Electronic or Semiconductor Engineering, Information Science or a closely related discipline.
• Relevant research or industrial experience in semiconductor/superconductor nanofabrication, cryogenic device design and testing, or heterogeneous integration.
• Familiarity with single-photon detection, heterogeneous integration and quantum technologies concepts preferred.
• Ability to work independently and collaboratively, with strong communication skills.

Required skills

• Preferred: photonic device/circuit design and simulation tools such as Lumerical or Ansys.
• Data acquisition and analysis, and scripting for instrument control (e.g. Python, MATLAB, LabVIEW).
