- Develop automated inverse design of silicon photonic components.
- Create control algorithms for photonics subsystems for real-world use cases.
- Assess fabrication variability and operational performance of silicon photonic components.
- Develop and implement testing and analysis methodology, including design-for-test, design-for-manufacturing, and design-of-experiments.
- Design and execute model creation for silicon photonics chips and subsystems based on measurement data.
- Close the loop between design and simulations.
What you'll need#
- Current enrollment in a PhD program specializing in Electrical Engineering, Physics, Photonics, or a related field.
- Understanding of silicon photonics or general photonics.
- Experience in electro-optic design of silicon photonics components.
- Ability to solve problems without obvious solutions.
- Exposure to automated design and analysis using Python scripting.
- Ability to translate data into actionable strategies and build structure through processes.
- Strong written and verbal communication skills.
- Capacity to comply with federally mandated requirements of U.S. export control laws.
- Preferred: Experience in design of high-speed transceiver systems, work with foundries, or exposure to designing PDK components.
Location & details#
- Location: Boston, Massachusetts.
- Term: Summer 2027.
- Modality: Hybrid.
- Employment: Full-time internship.
