NantOptiFab is building the only US foundry dedicated to Thin Film Lithium Niobate—creating LNOI wafers from raw crystal and processing them into finished photonic circuits. A US fab with 1,000+ tools producing thousands of TLFN wafers per month for telecom, defense, and quantum applications.
Our vertically integrated fab produces the key building blocks of thin film lithium niobate photonics—from passive waveguides to high-speed active devices.
We fabricate our own LNOI wafers from raw crystal via ion slicing and direct bonding, then etch rib and strip waveguides achieving propagation losses approaching 1 dB/m. Single-mode routing, bends, and splitters for dense photonic integration.
Mach-Zehnder and IQ modulators leveraging lithium niobate’s strong Pockels effect. Bandwidths exceeding 100 GHz with Vπ under 2 V, enabling 800G+ coherent links.
Precision domain engineering for quasi-phase-matched nonlinear optics. Entangled photon pair generation via SPDC, frequency conversion, and optical parametric amplification on chip.
Fiber-to-chip coupling, hermetic packaging, and hybrid integration with III-V lasers and detectors. Turnkey solutions from bare die to fully packaged photonic modules.
Lithium niobate’s unique combination of electro-optic, nonlinear, and low-loss properties makes it the ideal platform for quantum photonic systems.
High-speed feedforward switches, squeezed-light sources, and programmable linear-optical networks for measurement-based and boson-sampling quantum processors.
Integrated QKD transmitters with GHz-rate state preparation, ultra-low-loss channels, and on-chip entangled photon sources for metropolitan and long-haul secure links.
Frequency-conversion interfaces between telecom and quantum-memory wavelengths, entanglement distribution modules, and quantum repeater subsystems on TLFN.
Electro-optic sensors with sub-mV/m field sensitivity, integrated optical gyroscopes, and squeezed-light-enhanced interferometers for precision metrology.
Partner with the only dedicated TLFN foundry in the United States. From design to packaged die, we bring your photonic circuits to volume production.
