Chip designers are beginning to consider the possibility of designing computers based on photons instead of electrons.<\/p>\n\n\n\n

In 2018, scientists from three US universities<\/a> designed a chip that uses photonic input and output transmission. The chip itself continues to use normal electronics to function. The hybrid photonic\/electronic chip is a first step towards the use of photonics and attains data transmissions speeds of up to fifty times faster than conventional CPUs.<\/p>\n\n\n\n

Vladimir Stojanovi\u0107<\/a>, professor at the University of California, said that<\/a> “photonic specialized processors can save a tremendous amount of energy, improve response time and reduce data center traffic.”<\/p>\n\n\n\n

The next step is to build processors based on photons. At the University of Texas Austin earlier this year researchers announced the creation of a photonics-based arithmetic logic unit. Ray Chen<\/a>, computer scientist and lead researcher on the project, said that<\/a> “our optical computing devices have demonstrated speed beyond state-of-the-art processors, using much less power with lower latency, which means you can build a much faster computer that is more energy-efficient.”<\/p>\n\n\n\n

Another group from George Washington University<\/a> replaced GPUs with something they’re calling photonic tensor cores that are able to process opitcal data two to three orders faster than standard GPUs.<\/p>\n\n\n\n

Mario Miscuglio<\/a>, assistant professor at George Washington University, said that<\/a> “we found that integrated photonic platforms that integrate efficient optical memory can obtain the same operations as a tensor processing unit, but they consume a fraction of the power and have higher throughput and, when opportunely trained, can be used for performing inference at the speed of light. Photonic specialized processors can save a tremendous amount of energy, improve response time and reduce data center traffic.”<\/p>\n
