Anyone paying attention knows the world is running out of bandwidth, patience, and power. Data traffic keeps exploding, AI workloads keep ballooning, and geopolitical anxiety around tech dominance is the new normal. In that mess sits photonics, the field that quietly keeps the entire digital ecosystem from collapsing under its own weight. And in the middle of that field is Yunong Tang, a rising researcher in integrated lithium niobate photonic chips who works on the kind of hardware that will decide which countries stay competitive and which ones fall behind.
Actually, Yunong is not who you imagine when you think of today’s techie trailblazer’s. When she is not aligning lasers or debugging a fabrication run, she is somewhere on a mountain trail with a camera, chasing the kind of natural detail most people scroll past. The curiosity and discipline show up everywhere in her work. She looks at a waveform the same way she studies a ridgeline. Slowly. Intentionally. With a built-in refusal to accept the obvious answer.
Photonics, for anyone who has not been paying attention, now powers the modern world. It drives the internet through fiber optics, keeps data centers from melting down under AI demand, and plays a growing role in medical imaging and national defense. Integrated platforms like thin-film lithium niobate are no longer academic toys. They promise huge improvements in energy efficiency for data transmission and lay the groundwork for scalable quantum systems. The technology matters. A lot.
“It’s about building the tools that make everything else possible,” Yunong said. “If we can increase the performance and integration of lithium niobate devices, we can support secure communications, advanced computing, and better quantum sensing.”
This is not empty tech-bro futurism. Her work has already pulled interest from DARPA, the Office of Naval Research, and NIST. She built a lithium niobate ring resonator with a quality factor of one million. She demonstrated quantum emitter control through acoustic waves. She trained with AIM Photonics to sharpen her chip design and modulation expertise. Her next targets include modulators that push past 100 gigahertz and all-optical switches based on quantum Zeno effects.
The stakes are obvious. Countries are racing to localize chip production and secure their own communications infrastructure. The United States is finally throwing money at the problem through the CHIPS and Science Act and the National Quantum Initiative Act. Yunong’s research fits directly into that national strategy, especially for anyone concerned about energy consumption, foreign supply chains, or the fact that a single data center now uses enough power to run a small town.
Outside the cleanroom, she resets by hiking and taking photographs. The connection between the lab and the trail is not subtle. She studies light, patterns, and structure in both places. “Hiking and photography keep me grounded,” she said. “You learn to look closely. That kind of attention matters in research.”
Photonics may never get the attention that flashy AI startups enjoy, but the industry is headed toward multi-hundred-billion-dollar growth. Its influence touches everything from next-generation servers to secure communication systems to industrial lasers. And people like Yunong are shaping it with a mix of technical rigor and human curiosity that Silicon Valley could use more of.
She is part of a new wave of scientists who understand that innovation is not just about speed. It is about clarity, intention, and the patience to see complexity without flinching. Whether she is refining a chip or climbing a peak, she approaches both with the same mindset. Steady. Focused. Awake to the world she is helping create, one experiment and one trail at a time.
