The connection between Maxwell's equations and neural network opens exciting opportunities at the interface between photonics and machine learning. This feature issue of Photonics Research will highlight recent research progress at the intersection of photonics and machine learning and provide an opportunity for different communities to exchange cross-field ideas.
The tool of machine learning may revolutionize our capability for photonic design, and our understandings of complex photonic structures. Using neural networks for photonic design allows researchers to tap into a rich set of machine-learning algorithms, such as autoencoder, generative adversarial networks, attention models, transformer models, transfer learning, etc. which may enable highly efficient inverse photonic design.
Machine learning could also help to deepen our understanding of complex nanophotonic structures that derive their properties from a large network of inter-dependent nano-elements with both local and global connections. The vast parameter space offers unprecedented opportunities for device application, but at the same time presents a daunting challenge for developing an understanding of such complex structures.
Integrated photonics could provide a new way to advance computing in machine learning. The ever-increasing computing power required by digital neural networks prompted an effort to search for alternative computing methods that are faster and more energy-efficient. Optical analog computing can be passive with minimal energy consumption, and more importantly, its intrinsic parallelism can significantly accelerate computing speed. Nanostructured photonic devices can exploit sub-wavelength linear and nonlinear scatterers to realize complex input-output mapping far beyond the capabilities of traditional nanophotonic devices. Sophisticated vision tasks can be accomplished passively within the optical domain.
