(9)Michael Wei
Michael Wei is the CEO of Accelight Technologies, a Pleasanton, California ODM that designs and manufactures optical transceivers, EDFA amplifiers, and passive fiber components for telecom carriers and AI data centers. He is an electrical engineer with three decades in the trenches of optical networking hardware, with earlier stops at Mitel, ADVA Optical Networking, Adaptix, Navini Networks, Schlumberger, and Invocon.
Yichen Shen
Yichen Shen is the founder and CEO of Lightelligence, an MIT spinout building computers that run on light instead of electricity. A physicist who earned his PhD at MIT in 2016, Shen co-authored a landmark 2017 Nature Photonics paper showing that deep-learning math could be done with interfering photons, then turned the idea into chips. His company has shipped photonic processors (PACE), the first optical network-on-chip (Hummingbird), and optical interconnects (Photowave), and in 2026 became the first AI photonic-computing company to go public.
Matt Crowley
Matt Crowley is the CEO of SCINTIL Photonics, a fabless silicon-photonics company in Grenoble building single-chip DWDM laser engines for AI data centers. A Princeton-trained physicist who grew up in a family of small-business owners, he spent 25 years turning lab-stage technologies into volume products, founding and exiting two MEMS startups (Sand 9 and Vesper Technologies, the latter acquired by Qualcomm) before taking the helm at Scintil in late 2024. He argues the next bottleneck in AI is the network, not the chip, and is betting that light - not copper - will carry it.
Mian Zhang
Mian Zhang is the co-founder and CEO of HyperLight, the Cambridge-based deep-tech company commercializing thin-film lithium niobate (TFLN) photonics. A Cornell-trained physicist who did his foundational work in Marko Loncar's lab at Harvard, Zhang took a notoriously hard-to-manufacture optical material and shrank it onto silicon-style chips - cutting signal loss roughly 100-fold in work published in Nature. HyperLight now runs the industry's first high-volume, qualified 6-inch TFLN production line and is pushing 400G-per-lane photonic circuits into hyperscale AI data centers through partnerships with UMC, Wavetek, and Jabil.
Sanjai Kohli
Sanjai Kohli is the CEO of CSpeed Inc., a Palo Alto silicon photonics company building the future of datacenter connectivity. Best known as the architect of mass-market GPS, he co-founded SiRF Technology in 1995, whose chips eventually powered more than 70% of the world's consumer GPS devices. An IEEE Fellow and European Inventor Award winner, he holds dozens of US patents and has spent three decades founding and running companies in wireless, GPS, robotics and now AI networking.
Todd Swanson
Todd Swanson is the Chief Executive Officer of Proficium, a Union City, California-based company specializing in high-performance optical transceivers, fiber optic cables, and connectivity solutions for hyperscale data centers and AI/ML clusters. With over 30 years in optical networking, he brings deep expertise from Finisar (where he rose to Co-CEO and COO) and Intel (where he led Silicon Photonics as VP/GM). Appointed in August 2024 following Proficium's acquisition by Mill Point Capital, Swanson is steering the company through the AI-driven data center connectivity boom.
Nicolas Muller
Nicolas Muller is the co-founder and CEO of Arago, a Paris-based deep-tech startup building a photonic AI accelerator called JEF that uses light instead of transistors to perform AI inference at 10x lower energy than leading GPUs. Coming from a physics and machine learning background - including an ML degree from MIT - Muller co-founded Arago in 2024 alongside Eliott Sarrey and Ambroise Müller. The company raised an oversubscribed $26M seed round in July 2025 backed by Earlybird, Protagonist, Visionaries Tomorrow, and angels from Apple, Datadog, Hugging Face and Arm. Arago's approach - top-down from inference efficiency requirements, not bottom-up from optics research - delivered a working prototype in under 12 months.
Nicholas Harris
Nicholas Harris is the founder and CEO of Lightmatter, the photonic computing company rewriting the rules of AI infrastructure by replacing copper wires with light. A PhD from MIT's Quantum Photonics Lab, he grew up in the redwood forests of Gasquet, California, and turned years of academic research on programmable nanophotonic processors into a $4.4 billion company that has raised over $850 million from investors including Google Ventures and T. Rowe Price. With 87+ patents, 82 publications in Nature and its family of journals, and recognition as an Optica Fellow and MIT TR35 Innovator, Harris is building what he calls the next Moore's Law - not in transistors, but in optical interconnects.
Vivek Raghunathan
Vivek Raghunathan is the Co-founder and CEO of Xscape Photonics, a silicon photonics startup building multi-color laser technology to solve the bandwidth bottlenecks choking AI data centers. With a PhD from MIT and over 18 years of experience at Intel, Rockley Photonics, and Broadcom, he co-founded Xscape in 2022 alongside four Columbia University photonics researchers. The company has raised ~$95 million in total funding, backed by NVIDIA, Cisco, Addition, and IAG Capital Partners, and launched FalconX, the industry's first fully redundant eight-wavelength external laser module in pluggable form factor.
