The convergence of computation and storage through artificial synapses is a vibrant area of research, with notable attention directed toward photonic artificial synapses, particularly in emulating human visual perception and memory. However, many of these solutions necessitate both optical and electrical signals for bidirectional modulation. In this work, we report an optically responsive memristor (with a configuration of Ag:AgI/MA 0.4 FA 0.6 PbI 3 /Ag:AgI) that achieves bidirectional switching of resistive states utilizing 450 and 650 nm light at an ultralow readout voltage of 0.001 V. The maximum high-to-low resistive switching ratio can attain an impressive value of 74,459 at the readout voltage of 0.01 V, enabling comprehensive photonic bipolar modulation. The device presents artificial visual synapse (AVS) features in terms of short-term plasticity (STP)/long-term plasticity (LTP) to pulsed light in the range 300−700 nm. Under 450 nm blue light, an abrupt shift from low to high resistance can be observed, resembling the effect of glare. Intriguingly, the introduction of 650 nm red light can expedite recovery following blue light exposure. These attributes underscore the potential of the device for tasks encompassing color recognition, memory functions, and adaptation, suggesting promising prospects within artificial visual neural networks for ultraviolet and visible light sensing, transmission, and memory applications.

The visual system is crucial for human perception and learning, and the retina is responsible for pre‐processing visual information. Mimicking the neurobiological functions of the retina provides the basis for neuromorphic vision hardware. Here, an optogenetics‐inspired prototype capable of modifying neuron‐spiking behavior in a retina‐like manner is demonstrated. In addition to basic information processing, neuronal signal transmission in the retina is bio‐faithfully emulated using optical modulation, that is, neuronal firing is inhibited in the dark and activated upon illumination. The proposed single threshold‐switch field‐effect transistor optoelectronic neuron features an ultra‐compact design by integrating a gate‐modulated 2D MoS2 channel with a volatile threshold switch, and optoelectronic performance is achieved through a multi‐physics resistance‐matching mechanism. This study provides a promising pathway toward highly scalable and hierarchically designed spiking electronics, expanding the spectrum of neuromorphic hardware applications in the emerging field of biomimetic vision.

“…However, the conductance of memristors can primarily be reversibly adjusted through a combination of optical and electrical signals, whereas tuning solely by optical signals is rather limited. , Such optical and electrical combined operational scheme makes optoelectronic neuromorphic computing far less attractive . Therefore, an all-optically regulated memristor is highly desired.…”

Optoelectronic memristors are becoming increasingly attractive compared to traditional electrical memristors because they can effectively integrate the benefits of both photonics and electronics. However, the inability to reversibly tune the conductance with light has significantly hindered the development of optoelectronic neuromorphic computing. In this work, all-optically regulated resistive switching characteristics are demonstrated in the CMOS process-compatible ITO/ Cu 2 O/WO 3 /ITO optoelectronic memristor. The device exhibits an average transmittance of 70.14% under visible light. After electroforming, it achieves stable bipolar analogue switching, data retention beyond 10 7 s, and endurance of 10 6 cycles. An obvious increase in current is noticeable under 405 or 532 nm wavelength light irradiation, and the current decreases under 633 nm wavelength light irradiation. The light-tuned range is in μA. The synaptic plasticity learning behavior can be emulated in this memristor by electrical or optical stimulation. The learning, forgetting, erasure, and recovery processes of artificial intelligence are successfully implemented. Furthermore, based on the optical or electrical regulation of the conductances, the neural network simulation for supervising learning presents an online learning pattern recognition, and the accuracies can be achieved at 89.96 and 93.03% for optical and electric spikes, respectively. These results suggest that this memristor has high potential for optoelectronic neuromorphic computing applications.
