Abstract

We explore recent advancements in optoelectronic synaptic devices across four key aspects: mechanisms, materials, synaptic properties, and applications. First, we discuss fundamental working principles, including oxygen vacancy ionization, defect trapping, and heterojunction-based charge modulation, which contribute to synaptic plasticity. Next, we examine the role of 0D, 1D, and 2D materials in optimizing device performance, focusing on their unique electronic, optical, and mechanical properties. We then analyze synaptic properties such as excitatory post-synaptic current (EPSC), visual adaptation, transition from short-term to long-term plasticity (STP to LTP), nociceptor-inspired responses, and associative learning mechanisms. Finally, we highlight real-world applications, including artificial vision systems, reservoir computing for temporal data processing, adaptive neuromorphic computing for exoplanet detection, and colored image recognition. By consolidating recent developments, this paper provides insights into the potential of optoelectronic synaptic devices for next-generation computing architectures, bridging the gap between optics and neuromorphic engineering.

用于神经形态计算的光电突触装置的最新进展。
我们从四个关键方面探讨了光电突触器件的最新进展:机制、材料、突触特性和应用。首先,我们讨论了促进突触可塑性的基本工作原理,包括氧空位电离、缺陷捕获和基于异质结的电荷调制。接下来,我们将研究0D、1D和2D材料在优化器件性能方面的作用,重点关注其独特的电子、光学和机械性能。然后,我们分析了突触特性,如兴奋性突触后电流(EPSC)、视觉适应、从短期到长期可塑性的转变(STP到LTP)、伤害感受器激发的反应和联想学习机制。最后,我们重点介绍了现实世界的应用,包括人工视觉系统、用于时间数据处理的水库计算、用于系外行星探测的自适应神经形态计算和彩色图像识别。通过整合最近的发展,本文提供了对下一代计算架构中光电突触器件潜力的见解,弥合了光学和神经形态工程之间的差距。
