A technical paper titled “An All-Optical General-Purpose CPU and Optical Computer Architecture” was published by researchers at Akhetonics. Abstract: “Energy efficiency of electronic digital ...

Intel says its first optical computer interconnect system supports up to 4Tb/s bidirectional data transfer and is compatible with PCIe Gen 5.0.

“The all-optical computer realizes linear operations, nonlinear functions, and memory entirely in the optical domain with > 100 GHz clock rates,” they say. Their work paves the way for a new era of ...

Of course, scaling an all-optical computer capable of 100 GHz speeds to a consumer-friendly level is another factor, and researchers will undoubtedly have their work cut out for them.

The possibility of adapting the processor's reconfigurable nature to tasks like optical neural networks and photonic quantum computing suggests a versatile future for photonic systems.

The team, led by Prof. Mario Chemnitz and Dr. Bennet Fischer from Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena, has built a computer that uses light waves instead of silicon ...

The idea of optical computing—the use of photons instead of electrons to perform computational operations—has been around for decades. However, interest has resurged in recent years; the ...

One of the attractive features of early optical computer mice was their lack of moving parts. ... then a single chip image sensor/signal processor goes behind the lens.

The processor can be made using legacy manufacturing nodes in the 90-nanometer to 250-nanometer range. According to Akhetonics, that makes the chip relatively inexpensive to produce.

What a single Mach-Zehnder interferometer does in this context is a two-by-two matrix operation, performed on a pair of optical signals. With a rectangular array of those interferometers, the team ...

Intel says its work on switching from copper I/O to optical fiber has taken a big step forward in high-speed ... chiplet featuring an embedded Intel CPU in a demonstration that used live data for ...
