Ph.D. Intern - Silicon Photonics & Optical Communications

About Marvell Marvell’s semiconductor solutions are the essential building blocks of the data infrastructure that connects our world. Across enterprise, cloud and AI, and carrier architectures, our innovative technology is enabling new possibilities. At Marvell, you can affect the arc of individual lives, lift the trajectory of entire industries, and fuel the transformative potential of tomorrow. For those looking to make their mark on purposeful and enduring innovation, above and beyond fleeting trends, Marvell is a place to thrive, learn, and lead. Your Team, Your Impact The AI era runs on light. Every rack of XPUs training a frontier model, every hyperscaler connecting data centers across a metro region, every 1.6T optical module pushing data across a fiber at speeds that didn't exist three years ago — all of it depends on silicon photonics and optical DSP technology that Marvell designs. Marvell's optical team is one of the few places in the world where silicon photonics, coherent DSP, PAM4 signal processing, and co-packaged optics integration are all happening under one roof, at production scale, for the world's largest AI infrastructure operators. The work spans every layer of the AI interconnect hierarchy. At the scale-up layer — connecting XPUs within a rack or cluster to behave as a single logical compute unit — the team is developing silicon photonics light engines for Co-Packaged Optics and Near-Packaged Optics platforms that eliminate the reach and power limitations of copper at the shortest distances.
