Key Responsibilities

  • Design and implement automated control and data-acquisition systems for poling processes, confocal-based domain imaging, and fiber-to-chip coupling characterization.
  • Establish high-throughput workflows for wafer-scale device screening, including evaluation of poling quality, optical loss, and coupling efficiency.
  • Integrate and synchronize optical, electrical, and mechanical instrumentation into a coherent and robust automation framework.
  • Optimize system performance in terms of measurement speed, reproducibility, and scalability for large-area device evaluation.
  • Translate fabrication variability into systematic testing and feedback strategies to improve device yield and performance.
  • Collaborate closely with fabrication teams to support process development and device optimization for TFLN photonics.

Requirements

  • PhD in Photonics, Electrical Engineering, Applied Physics, or a related field.
  • Strong background in integrated photonics, with preference for experience in lithium niobate (TFLN) or related platforms.
  • Proven experience in laboratory automation, including instrument control, data acquisition, and system integration.
  • Strong programming skills (e.g., Python, LabVIEW, or equivalent) for developing automated measurement and control systems.
  • Hands-on experience with optical characterization techniques (e.g., laser-based measurements, fiber coupling, confocal microscopy).
  • Familiarity with ferroelectric domain engineering, poling processes, or nonlinear/quantum photonic devices is highly advantageous.
