We find that a commonly-used distributed feedback laser diode (DFB-LD) can work as a graded-potential-signaling photonic neuron. Through theoretical and experimental demonstration, DFB-LDs are proved useful for three graded-potential-signaling-based neuromorphic processing applications of the pattern recognition, the single-wavelength implementation of spike timing dependent plasticity (STDP), and the sound azimuth measurement. The pattern recognition with a full-width-at-half-maximum (FWHM) of 1 μs is realized in the experiment.

用作梯度电位信号光子神经元的分布式反馈激光二极管的演示及其在神经形态信息处理中的应用

我们发现，常用的分布式反馈激光二极管（DFB-LD）可以用作梯度电位信号光子神经元。通过理论和实验证明，DFB-LD被证明对模式识别，基于单脉冲实现的尖峰时序可塑性（STDP）和声音方位角测量的三种基于梯度电位信号的神经形态处理应用有用。在实验中实现了半峰全宽（FWHM）为1μs的模式识别。
