Unlocking the potential of Lithium niobate PICs

Thin film Lithium Niobate

Lithium niobate (LN) is a widely recognized high potential next generation PIC material due to its unique material properties, replacing Si and InP in ultra-high speed datacom and enabling new applications in quantum computing and AI. The advent of thin film LN wafers, referred to as Lithium Niobate on Insulator (LNOI), represents a significant leap forward in realizing LN based PICs. Unfortunately, the full potential of LN in PICs has not been delivered yet, due to the challenges of PIC fabrication on LNOI. Furthermore, PIC development in general is typically associated with long lead times and high cost, resulting in excessive development cost, high risk and unfeasible business cases.

Our Technology

Rapid Photonics has solved these problems through a patented revolutionary PIC production technology: DEpicT® (Direct Etch-less photonic integrated circuits Technology) that overcomes the challenges of LNOI PIC fabrication. DEpicT delivers low-loss waveguides in LNOI with high yield and short lead time at affordable cost. Our technology is 100% CMOS compatible, facilitating seamless scale up of PIC production in conventional Si PIC foundries. We have our own fabrication capacity and collaborate with selected partners for electrical and optical integration, packaging and testing. This enables us to provide our customers with fully functional LNOI PIC components for their specific application.

Currently, our technology supports the integration of passive and active photonic components such as Mach-Zehnder modulators, ring resonators, couplers, etc. Other active components such as surface acoustic wave modulators, amplifiers, and comb generators are in development.

DEpicT is also applicable to silicon nitrate PICs, enabling customers to leverage on the short lead times and highly competitive cost of DEpicT in comparison to conventional silicon nitrate PIC production processes.
