Research Fellow in Integrated Nonlinear and Quantum Photonics (Quantum Light Sources and Waveguide Single-Photon Detectors), NUS
Job Description
NUS Electrical and Computer Engineering is hiring a Research Fellow in integrated nonlinear and quantum photonics. The project combines quantum light generation, manipulation, transmission and single-photon detection on one chip. It has three strands: efficient nonlinear devices in van der Waals–silicon nitride hybrid waveguides; superconducting single-photon detectors integrated with waveguides; and efficient photon-pair sources in periodically poled lithium tantalate. You would handle modelling, design, nanofabrication and optical testing.
