An all-optically tunable neuromorphic imaging element based on black phosphorus (BP) is demonstrated by Taimur Ahmed, Sumeet Walia, and co-workers in article number 2004207. The unusual wavelength-dependent photocurrent in BP is harnessed to optically program and erase visual memory elements. Concurrently, the same elements are capable of in-pixel image preprocessing in an imaging array and optoelectronic machine learning for pattern classification and image recognition through deploying artificial neural networks.
