Postdoctoral Fellow; PREP

PREP Research Associate – The National Institute of Standards and Technology (NIST) is recruiting a postdoctoral researcher to work on photonic integrated circuits (PICs). The role involves developing optimized photonic test structures that will be incorporated in PIC process flows, enabling extraction of key physical parameters such as absorption, scattering loss, and refractive index dispersion. Test structures will be optimized for use in PICs based on the silicon‑in‑insulator, silicon nitride, and thin film lithium‑niobate platforms.

• Perform a literature review to assess existing test structure designs and methodologies for PIC parameter extraction.
• Set up electromagnetic simulation models of existing test structure geometries to enable simulation and optimization for specific PIC platforms.
• Investigate methods to optimize test structure designs for more robust determination of photonic parameters.
• Produce layouts and work with team members on fabrication and measurement of optimized test structure designs.
• Present results at internal meetings and occasional meetings with external stakeholders such as at photonics conferences or through peer‑reviewed journal publications.
• Ensure that results, protocols, software, and documentation have been archived or otherwise transmitted to the larger organization.

• A PhD in Electrical and Computer Engineering, Applied Physics, or a related field.
• More than 3 years of experience with Lumerical and COMSOL electromagnetic simulation tools.
• Experience with device design and layout for photonics foundries.
• More than 2 years of experience with photonic device characterization including linear spectroscopy.
• Familiarity with multiple scripting languages such as Matlab, C, and Python.
• Strong oral and written communication skills.

• CV/Resume (limit to 3 pages and include only a valid email address for contact; do not include telephone numbers, home address, or photos).
• Two professional references.
