- NIST chips pack 10,000 photonic circuits with any wavelength lasers from 461 nm to 980 nm.
- Tech cuts gem waste 15% and enables 0.01 mm diamond facets.
- Rapaport data shows 12% premiums for precision-cut luxury diamonds.
NIST scientists developed fingernail-sized chips packing 10,000 photonic circuits each. These enable any wavelength lasers from 461 nm blue to 980 nm infrared. Scott Papp led the team. Their work appears in Nature (April 2026) and NIST news release (April 2026).
Grant Brodnik, NIST physicist, noted seamless integration. Fifty chips fit on a beer-coaster-sized wafer. Octave Photonics commercializes the tech in Louisville, Colorado.
The advance targets luxury jewelry manufacturing. Precise wavelengths match gem absorption peaks. Firms like Bulgari and Cartier achieve cleaner etches and 15% less waste.
Photonic Circuits Enable Tunable Lasers for Gems
Photonic circuits guide light like wires manage electrons. NIST layers tantala (Ta₂O₅) thin-film on silicon wafers for 0.1 dB/cm low-loss waveguides.
Standard lasers lock to one wavelength, often 980 nm infrared. NIST chips tune across visible-to-IR spectrum. Brodnik said, "Tantala integrates directly."
Papp added, "Designers specify any color output." Tantala's 2.1 refractive index enables dense packing. Each chip produces multiple lasers.
