About the Author
Let’s be real, I’m not an expert in this industry. But I’ve been in the trenches as an engineer, designer, and systems hacker. I’ve built tech, integrated chaos, and mentored over 3,000 startups (from underwater basketweaving, industrial automation, hydrogen fuel cells, to biotech and medical devices) across 10+ scrappy emerging ecosystems. I’ve seen mindset traps, resource gaps, tribal gatekeeping from those afraid to lose control, and thankfully, breakthrough innovation.
I’ve also spent two decades inside the abundance of mindset-driven Silicon Valley. That experience rewired how I see potential.
What am I an expert in? Curiosity. Patterns. Ecosystems. Opportunity.
I believe our region is sitting on untapped potential. We need bold moves, not business-as-usual. An innovation hub here could change the game, slowing brain drain, fueling talent, and creating the kind of economy that works for more of us.
This series isn’t about theory. It’s about lighting a fire. Let’s collaborate bigger, move faster, and make some noise.
Light-Based Technologies in the Manufacturing Landscape
At its core, photonics is light generation, manipulation, and detection. In semiconductor and advanced manufacturing, this involves:
- Projecting patterned light to etch nanometer-scale circuits.
- Using lasers to heat, cut, weld, or build components.
- Measuring dimensions, defects, and material composition with optical sensors.
- Moving and analyzing massive amounts of data via light-based interconnects and vision systems.
From laser-based lithography to fiber-optic sensing, the manufacturing ecosystem is undergoing a quiet revolution fueled by photons.
Light Sources: The Engine of Photonic Systems
Various light sources power the full spectrum of manufacturing functions:
