Student Project: Robust algorithms for external calibration of OPAs

Optical Phased Arrays (OPAs) are integral to the functionality of LiDAR systems and find use in a diverse range of standalone applications. At IMEC, we have pioneered the development of OPAs with innovative designs on our platforms. Like most of the precision optical devices, OPAs require calibration post-fabrication or on a regular basis. While the standard calibration methods integrated within OPAs suffice for routine calibrations, a variety of practical scenarios necessitate or favor alternative calibration techniques. This project is committed to a thorough investigation of the external calibration of OPAs. It encompasses the exploration of the need for external calibration algorithms, various methods, modelling, and validation of the performances of the external calibration algorithms.

What you will do

In your role, you will begin by understanding the basics, such as the operation of OPAs, current calibration techniques, modelling of phase control algorithms, establishing performance metrics for these algorithms, and implementing them into IMEC's devices. Your engagement will encompass the tasks listed below: 

• Understanding Fundamentals: Understand the operation of OPAs and familiarize yourself with current calibration techniques. Analyze the built-in calibration methods of OPAs to identify their limitations in practical scenarios.
• Modeling: Develop mathematical / simulation models to study the calibration process for OPAs.
• Algorithm Development: Create and/or adapt robust algorithms for external calibration, focusing on their accuracy, efficiency, and adaptability.
• Experimental Verification: Conduct experiments to verify the performance of the developed algorithms using real OPAs. Evaluate these algorithms against predefined performance metrics and compare them to existing methods.
• Documentation and Best Practices: Maintain good programming practices throughout the project and ensure documentation of relevant processes and findings.

What we do for you

You will be working on an industrially relevant interesting topic. We offer a flexible environment with independence and support from the experts of the field. As part of the PICS(Photonic Integrated Circuit/System) team in IMEC-Netherlands you will have opportunities to collaborate and learn from some of the best minds in PICs as well as other research domains.

Who you are

• You are a Master's student with a background in Optics/Physics or an Engineering background with a strong interest and knowledge in optics.
• You are available for a 12-month period, which includes time for thesis preparation.
• You have the legal right to undertake an internship in the Netherlands.
• You are a self-starter with the ability to work autonomously.
• You possess a solid foundation in mathematics, including linear algebra and statistics.
• You have skills in programming (Python or Matlab) and data analysis. Familiarity with version control is an advantage.
• Knowledge of signal processing and control systems is beneficial.
• Hands-on experience with optical experiments (free-space or fiber-based, including lasers and photodetectors) is advantageous.
• An interest and capability in authoring conference/journal papers is desirable.
