Diffractive Optical Network

Diffractive optical networks (DONs) leverage the principles of diffractive optics and deep learning to perform complex computational tasks all-optically, bypassing the need for electronic processing. Current research focuses on designing DON architectures for specific applications, including image processing (magnification, demagnification, multispectral imaging), data encryption, and even decision-making and control, often employing pyramidal or rotation-multiplexed designs. These networks offer advantages in speed, energy efficiency, and compactness compared to electronic counterparts, with potential impact across diverse fields such as telecommunications, biomedicine, and artificial intelligence.
