用于并行和非线性处理的梳状光子神经种群

Comb-based photonic neural population for parallel and nonlinear processing

Bowen Ma, Junfeng Zhang, Weiwen Zou

摘要:

人们认为,神经信息的表示和处理依赖于神经群体而不是单个神经元。在神经形态光子学中,以非线性响应形式存在的光子神经元在单个器件和时间节点中得到了广泛的研究。然而,为了构建光子神经种群(PNP),考虑到物理复杂性和响应延迟,放大和大规模互连的过程仍然具有挑战性。在这里,我们提出了一个梳状PNP互连的载波耦合具有卓越的可扩展性。理论和实验证明了梳状PNP中神经元群体的两个独特性质,包括非线性响应曲线和群体活动编码。实验成功地实现了一个具有双射频(RF)音调的三个输入模式的实时分类任务,表明基于梳状结构的PNP可以有效地利用光子学的超宽带进行并行和非线性处理。

英文摘要:

It is believed that neural information representation and processing relies on the neural population instead of a single neuron. In neuromorphic photonics, photonic neurons in the form of nonlinear responses have been extensively studied in single devices and temporal nodes. However, to construct a photonic neural population (PNP), the process of scaling up and massive interconnections remain challenging considering the physical complexity and response latency. Here, we propose a comb-based PNP interconnected by carrier coupling with superior scalability. Two unique properties of neural population are theoretically and experimentally demonstrated in the comb-based PNP, including nonlinear response curves and population activities coding. A classification task of three input patterns with dual radio-frequency (RF) tones is successfully implemented in a real-time manner, which manifests the comb-based PNP can make effective use of the ultra-broad bandwidth of photonics for parallel and nonlinear processing.
