Robert Devlin and the lens that learned to lie flat
A childhood spent building radios led Robert Devlin to a different kind of signal. At Metalenz, he is turning nanoscale patterns into optics that can be made by the million - and asking what phones could see next.
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.
Li Zhu
Li Zhu is the founder and CEO of Deptrum (光鉴科技), a 3D vision company building full-stack depth-sensing hardware and software powered by nanophotonics and AI. A Tsinghua undergraduate and UC Berkeley PhD in nano-optoelectronics, he led the depth camera module team behind Apple's iPhone X Face ID before leaving in 2018 to build a structured-light approach that sidesteps Apple's patent monopoly. Deptrum's depth cameras now ship into smartphones, smart cockpits, robots, IoT devices and palm-payment systems, and the company has raised through a Series B.
Rob Devlin
Rob Devlin is the co-founder and CEO of Metalenz, the first company to take metasurface optics out of the lab and into mass-market consumer devices. A Harvard-trained applied physicist who studied under Federico Capasso, he turned a Science cover paper into a fabless optical-semiconductor company that prints flat lenses in standard chip foundries. Under his leadership Metalenz shipped the world's first metasurfaces in consumer products with STMicroelectronics in 2022 and launched Polar ID, a polarization-based face authentication system. He keeps the first wafer of 10,000 metasurface lenses on his desk as a reminder of how a single fabrication shot eclipsed an entire PhD's worth of handmade devices.
