Researchers have developed a fully photonic convolutional neural network (PCNN) capable of executing image classification tasks entirely within the optical domain. This novel architecture integrates convolution, max-pooling, nonlinear activation, and fully connected layers using optical components like Mach-Zehnder Interferometer meshes and microring resonators. While achieving 94.49% accuracy on the MNIST dataset, a digital twin with ex situ pre-training reached 97.45% accuracy. The PCNN demonstrates significant potential for energy efficiency, with an estimated 220 to 330 times greater efficiency than state-of-the-art electronic GPUs for single-image inference, alongside a low inference latency of 843 ns.
