Broadband Optoelectronic Synapse Enables Compact Monolithic Neuromorphic Machine Vision for Information Processing

Abstract Traditional machine vision is suffering from redundant sensing data, bulky structures, and high energy consumption. Biological‐inspired neuromorphic systems are promising for compact energy‐efficient vision. Multifunctional optoelectronics enabling multispectrum sensitivity broadband image sensing, feature extraction, computing vital visions. Here, an optoelectronic synapse designed that enables convolutional processing, computing. Multiple synaptic plasticity triggered by photons can implement photonic information transmission. Convolutional processing realized ultralow kernel generators fully controlled photons. Meanwhile, the device shows ability of conductance modulations under electronic stimulations For first time, this two‐terminal front‐end retinomorphic back‐end The integrated encryption, preprocessing, capabilities monolithic systems.
