Job Description
The team of Prof Loh Kian Ping is seeking a highly motivated Research Fellow to lead the development of a miniaturized, on-chip polarimeter based on chiral 2D Halide Organic-Inorganic Perovskites for full Stokes vector detection. The candidate will focus on optical simulation, cleanroom nanofabrication, device integration, optoelectronic testing, and machine learning-driven signal reconstruction.
Note: This role focuses on device engineering and computation; independent material synthesis is not required.
Key Responsibilities:
• Design & Simulation: Model sub-wavelength polarization-selective metasurfaces using electromagnetic simulation tools (FDTD/FEM) to establish optoelectronic eigenvectors.
• Nanofabrication: Fabricate multi-pixel sensor arrays and integrate pre-synthesized chiral 2D HOIP layers into metasurface architectures in a cleanroom environment.
• Optoelectronic Characterization: Build and operate automated optical benches to test multi-pixel photocurrent responses under varied polarization states.
• Data Analysis & ML: Develop Python/MATLAB machine learning algorithms to map photocurrents to full Stokes parameters, targeting a reconstruction error of (<1%).
Required Qualifications:
• Ph.D. in Electrical Engineering, Applied Physics, Materials Science, Optical Engineering, or a related field.
• Strong background in nanophotonics, metasurfaces, and polarization optics (Stokes vectors).
• Hands-on cleanroom fabrication experience (EBL, photolithography, thin-film deposition).
