- Non-linear operations are essential for general-purpose processors and are challenging in optics, especially on a chip.
- The technology leverages photonic integrated circuits (PICs) to generate these non-linearities, enabling all-optical cross-domain compute capabilities.
- Integrated non-linear optical components allow for complex devices: digital optical logic gates, analog mathematical operations, and quantum feed-forward for continuous variables.
- Optical memory can also be created using these components.
- Combining these building blocks enables general-purpose digital optical CPUs, analog optical AI accelerators, or optical quantum computers.
- Cross-domain integration is facilitated by components like all-optical analog-digital converters (ADCs), enabling optical digital control flow combined with analog mathematics.
- The architecture surpasses von Neumann, integrating analog and quantum computing for next-generation processing.
- Optical XPUs offer unlimited parallelization via additional cores or wavelength multiplexing, boosting performance without increasing power consumption.
- Low power consumption results in minimal heat output, eliminating the need for advanced cooling solutions.
- Rugged, high-performance, low-power compute solutions can be deployed at the edge, outside traditional data centers.
