VectorScribe LLC is a Bethlehem, Pennsylvania photonics startup built around making advanced optical microfabrication more accessible. It uses proprietary, maskless laser direct writing to create custom optical microstructures for researchers and companies developing authentication features or testing new optical designs, with prototype turnaround typically about a week.
Nabu Optical SystemsFounded in 2022 from University of Dayton photonics research, Dayton-based Nabu Optical Systems develops maskless optical lithography tools for semiconductor prototyping and production. Its platform uses virtual masks to combine projection lithography’s speed with direct laser writing’s flexibility, serving startups, research institutions and smaller chip manufacturers that need a more accessible path to fabrication. The company won the startup competition at the 2025 International Conference on Electron, Ion, and Photon Beam Technology and Nanofabrication.DUBLIN, OH
Cybel, LLCFounded by Drs. Jean-Marc Delavaux and Glen Williams, independently owned Cybel designs and fabricates fiber lasers and fiber amplifiers in Bethlehem, with an R&D center in Fairfax, Virginia. Its systems serve OEM and benchtop applications across the 1, 1.5, and 2 micrometer bands, including the compact MAKO and higher-power SKYLINE platforms. Cybel also acts as a North American distributor for complementary photonics manufacturers, extending its reach beyond its own laser and amplifier line.BETHLEHEM, PA

Avo PhotonicsFounded in 2003 by physicist Joseph L. Dallas, Avo Photonics designs, develops, and manufactures optoelectronic products for customers who retain ownership of their intellectual property. The Philadelphia-area contract manufacturer works from concept through scalable U.S. production, with a 40,000-square-foot cleanroom facility and a strict confidentiality model that keeps Avo from competing with its clients. Avo is ISO 9001:2015 and ISO 13485:2016 certified and ITAR registered.HORSHAM, PA
