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...
Imprinting vision as memory is a core attribute of human cognitive learning. Fundamental to artificial intelligence systems are bioinspired neuromorphic vision components for the visible and invisible segments of the electromagnetic spectrum. Realization of a single imaging unit with a combination of in‐built memory and signal processing capability is imperative to deploy efficient brain‐like vision...
