TOPIC - High Bandwidth

High bandwidth solution for photonic encryption

Bringing photonic encryption up to speed

Optalysys is developing a new approach to fully homomorphic encryption (FHE), using photonic technology to handle the enormous computational demands involved.

But unlocking that potential created another challenge: exchanging and processing data between the photonic chiplets and the electronics at extremely high speeds.

TOPIC developed the high-bandwidth interface needed to bring both worlds together, combining FPGA, board design and mathematical modelling expertise with the latest AMD RFSoC technology.

Closing the bandwidth gap

The Optalysys Etileā„¢ photonic chiplet provides the computational power behind its FHE technology. But to make full use of that speed, large amounts of data need to move between the photonic chiplets and the controlling FPGA just as fast.

Using AMD RFSoC technology, TOPIC developed the high-bandwidth analog interface needed to exchange, convert and process these data streams.

Complex mathematical models were translated into fast, resource-efficient FPGA logic, allowing the electronics to keep pace with the photonic processing.

Step 3: Feasability

Making secure data processing practical

By combining Optalysys' photonic technology with TOPIC's FPGA and board design expertise, the solution connects extremely fast optical processing with the electronics needed to use it in real-world applications.

The next ambition is to further miniaturize the FPGA-based electronics for integration into data center infrastructure.

A step towards making high-performance fully homomorphic encryption practical for secure cloud data processing and exchange.
