About the Role
The AI era runs on light. Marvell's optical team designs silicon photonics and optical DSP technology essential for AI infrastructure. This role involves working on cutting-edge projects at the intersection of photonics, high-speed signal processing, and advanced semiconductor integration, with the opportunity to see your research become working optical silicon deployed at scale.
Responsibilities
- Design, simulate, and characterize silicon photonics components and subsystems for integration into PAM4 and coherent transceiver platforms.
- Develop and validate DSP algorithms for high-speed optical links, including equalization, FEC, and signal integrity techniques.
- Work on optical system modeling and link budget analysis for data center interconnect, co-packaged optics, and near-packaged optics applications.
- Collaborate with analog IC design, packaging, and systems engineering teams to integrate photonic and electronic components.
- Characterize and validate designs in the lab using high-speed test equipment, optical measurement tools, and silicon bring-up setups.
- Participate in a structured design curriculum and present research findings and design results to the engineering team.
Requirements
- Currently enrolled in a Ph.D. program in Electrical Engineering, Applied Physics, or a related field, with a research focus in photonics, optical communications, or high-speed signal processing.
- Hands-on research experience in photonics, optical communications, or high-speed signal processing.
- Demonstrate research experience in silicon photonics device design and simulation, optical transceiver systems, coherent or direct-detect optical communications, or DSP algorithm development for high-speed links.
- Apply strong fundamentals in photonics and electromagnetics (waveguide theory, modulator physics, photodetector design, or optical link analysis).
- Use simulation and modeling tools relevant to your research area (FDTD, MODE, Lumerical, MATLAB, or equivalent) with confidence and independence.
- Communicate research findings and design tradeoffs clearly.
