A physicist by training and a patient operator by temperament, he has spent more than two decades pulling a niche piece of laboratory physics, spatial-spectral holography, out of Montana State University and into the hands of the U.S. Department of Defense, DARPA, and the intelligence community.
Michael LaFramboise
Michael LaFramboise is the CEO and co-founder of Aurelius Systems, a San Francisco defense startup building autonomous, AI-guided laser turrets that detect and destroy drones at the speed of light for roughly pennies per shot. A Case Western engineer, Navy veteran, and ex-Coherent and Amazon Devices operator, he dropped out of a Columbia PhD in nano optical systems to build Archimedes, a low-cost directed-energy weapon. Aurelius raised a $10 million seed co-led by General Catalyst and Draper Associates in September 2025 and opened a U.S. manufacturing line for high-power fiber lasers in 2026, aiming to become America's domestic one-stop laser shop.
Zaijun Chen
Zaijun Chen is a physicist-turned-founder building light-powered computers for artificial intelligence. As co-founder and CEO of Opticore, he is developing photonic optical processing units (OPUs) that the company says are up to 100x more energy efficient and 25x denser than leading GPUs. Trained at the Max Planck Institute of Quantum Optics and MIT, and now director of the Laboratory of Intelligent and Quantum Photonics at USC, Chen turned a decade of precision-optics research into a venture-backed bet that the future of AI compute runs on photons instead of electrons.
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.
