Photonics & Metalenses
RI materials for metalenses, diffractive optical elements, and integrated photonic circuits. NIL-compatible. R2R scalable. PFAS-free.
Metalens replication
Flat optics at R2R production scale
Metalenses replace curved glass optics with flat nanostructured surfaces. They require ultra-high RI materials (n > 1.9) that can be precisely nanostructured via NIL. Kriya’s TiO2 nanocomposite formulations reach RI 2.00 in UV-curable, NIL-compatible form — enabling metalens fabrication on R2R lines rather than in semiconductor fabs.
Metalens: RI 1.16-2.00
Various chemistry families and curing technologies. NIL-compatible for sub-wavelength nanopillar structures.
Both thermal and UV-curable
Thermal variants 130-350 deg C. UV variants enable sub-second cure for high-throughput NIL replication.

Integrated photonics
Beyond Moore: light replaces electrons
On-chip photonic interconnects, optical neural networks for AI acceleration, and photonic qubits for quantum computing all require materials with precisely controlled refractive indices. Kriya’s RI 1.16 to 2.00 platform provides the complete materials toolkit for integrated photonics.

Diffractive optical elements
Precise RI control for every optical layer
Diffractive optics, holograms, and beam-shaping elements all depend on controlled RI gradients. Kriya’s four chemistry families — sol-gel, UV-curable solids, UV-curable hybrids, and thermal-curable latex — provide the formulation flexibility to hit any RI target from 1.16 to 2.00 with the processing characteristics each application demands.
Sol-gel
