Recent progress in optoelectronic memristive devices for in-sensor computing

Neuromorphic computing system, inspired by human brain, has the capability of breaking through the bottlenecks of conventional von Neumann architecture, which can improve the energy efficiency of data processing. Novel neuromorphic electronic components are the hardware foundation of efficient neuromorphic computation. Optoelectronic memristive device integrates the functions of sensing, memorizing and computing and is considered as a promising hardware candidate for neuromorphic vision. Herein, the recent research progress of optoelectronic memristive device for in-sensor computing are reviewed, including optoelectronic materials and mechanism, optoelectronic memristive device/characteristics as well as functionality and application of in-sensor computing. We first review the optoelectronic materials and corresponding memristive mechanism, including photon-ion coupling and photon-electron coupling type. Then optoelelctronic and all-optical modulated memristive device are introduced according to the modulation mode. Moreover, we exhibit the applications of optoelectronic device in cognitive function simulation, optoelectronic logic operation, neuromorphic vision, object tracking, etc. Finally, we summarize the advantages/challenges of optoelectronic memristor and prospect the future development.
