Unlocking the potential of Lithium niobate PICs

Open Foundry for Lithium niobate PICS

Rapid Photonics is an open foundry for the design, production and verification of lithium Niobate on Insulator (LNOI) PICs. Our revolutionary DEpicT® technology (Direct Etch-less photonic integrated circuits Technology) enables the production of low-loss waveguides in LNOI with high yield and short lead-time, unlocking the unique potential of Lithium Niobate in PIC applications.

DEpicT® technology delivers compact PICs with a waveguide density and bending radius comparable to conventional PIC technologies. Currently, our technology supports the integration of passive photonic components. Active components, such as Mach-Zehnder interferometers, electro-optical switches, amplifiers, are in development.

Rapid Photonics enable academic as well as industrial researchers in the field of Quantum Photonics and Reconfigurable PICs to execute LNOI PIC development with a short iteration cycle.
