The Team

Vivek Raghunathan

Co-Founder and CEO

Vivek has over 15 years of experience in silicon photonics. He was a Sr. Principal Engineer, Product Architect and Program Leader for Integrated Silicon Photonics at Broadcom driving key core technology development required to co-package optics with switches and demonstrated industry’s first 25.6T Ethernet switch co-packaged with silicon photonics chiplets. Prior to joining Broadcom, he was a Principal Engineer at Rockley Photonics where he led silicon photonics product integration for their data-com product line. He started his career at Intel where he led next generation GPU to HBM interconnect technology development and the commercialization of their first Silicon-photonics-based transceivers. He received his PhD from MIT in Material Science and Engineering.
