Abstract

We investigate the dynamic behaviour of resonant tunneling diode-photodetectors (RTD-PDs) in which the excitability can be activated by either electrical noise or optical signals. In both cases, we find the characteristics of the stochastic spiking behavior are not only dependent on the biasing positions but also controlled by the intensity of the input perturbations. Additionally, we explore the ability of RTD-PDs to perform optical signal transmission and neuromorphic spike generation simultaneously. These versatile functions indicate the possibility of making use of RTD-PDs for innovative applications, such as optoelectronic neuromorphic circuits for spike-encoded signaling and data processing.

摘要

我们研究了共振隧穿二极管光电探测器（RTD-PD）的动态行为，其中可通过电噪声或光信号激活其兴奋性。在这两种情况下，我们发现随机尖峰行为的特性不仅取决于偏置位置，还受输入扰动强度的控制。此外，我们还探索了RTD-PD同时执行光信号传输和神经形态尖峰生成的能力。这些多功能特性表明了将RTD-PD用于创新应用的可能性，例如用于尖峰编码信号和数据处理的光电神经形态电路。
