Four dedicated fabs. One connected system.
NantOptiFab designs, fabricates, packages, and tests photonic integrated circuits through specialized California facilities spanning lithium niobate, nonlinear photonics, silicon nitride, and silicon photonics.
Specialized around the material
Each fab concentrates the processes and equipment needed by its platform while sharing design, backend, packaging, metrology, and quality infrastructure across the full manufacturing system.
LN & TFLN Fab
3,000+wafers per month
High-speed electro-optic modulators, coherent devices, and ultra-broadband transceivers.
ELN™ & PPLN Fab
3,000+wafers per month
Enhanced electro-optics, wavelength converters, and quantum photon sources.
Silicon Nitride Fab
10,000+wafers per month
Ultra-low-loss devices, passive routing, and wafer-level photonic interposers.
Silicon Photonics Fab
5,000+wafers per month
800G/1.6T CPO modules, integrated Tx/Rx, and AI-interconnect PICs.
Combined capacity exceeds 20,000 wafers per month across the four dedicated California fabs.

100% USA supply-chain positioning
NantOptiFab is a California-based photonics company building American multi-platform photonic manufacturing, from material platforms through packaged modules.
California foundation
Engineering, manufacturing, packaging, and customer engagement are centered in California and the United States.
Fewer handoffs
Materials, process development, device design, wafer fabrication, backend, packaging, and test are coordinated under one manufacturing organization.
Built for partners
Fabless PIC designers, system integrators, universities, and downstream product teams can engage at the stage that matches their program.
