Researchers of the University of Tokyo have reported a new method of optical calculations that has the potential to significantly increase the power and energy efficiency of computers compared to modern electronic devices. Scientists believe that such computers could become a reality within the next ten years.
The newly developed method, known as “Diphyxiation Formation,” allows for the use of light to perform calculations instead of electricity. This innovation not only helps in avoiding the heat release associated with traditional electronic devices but also removes size limitations on computing elements. This approach is particularly well-suited for image processing and machine learning tasks.
Diphyxiation formation is built upon the “Throwing Retrans” method, which was initially developed in the 1980s but has been significantly improved upon. Unlike the outdated approach, the new method leverages the properties of light waves, making computing elements more flexible and spatially efficient. The process of using layers of light waves to carry out calculations has been likened to “laying layers in Photoshop.”
Researchers are confident that this method can complement existing computing systems by handling specialized tasks and contribute to the advancement of future technologies, such as quantum computing. The potential of this method has already been demonstrated through the performance of 16 basic logical operations using this approach.
While the system is currently in the early stages of development, it is anticipated that the commercial implementation of optical computers may commence within the next decade, paving the way for a new generation of computational technologies.
The diphyxiation formation method is detailed in an article published in the peer-reviewed journal Advanced Photonics.
