摘　　要：脉冲神经网络与传统人工神经网络相比,具有硬件友好性和低能耗的优点。而光子脉冲神经网络与电脉冲神经网络相比具有速度快、能耗低、传输容量大和抗电磁干扰能力强等优点。基于半导体光放大器(SOA)设计了一种新的光子脉冲神经元模型—LIF(泄漏积分与发射)模型,实现了信号的加权、延迟、积分和阈值判决等功能,并在此基础上探索了该LIF模型在数字逻辑中的应用。实现了基于该模型的“异或”逻辑功能,并改进了一种具有兴奋性和抑制性神经元,通过光通信仿真软件得到LIF模型、“异或”逻辑和具有兴奋性和抑制性神经元良好的输出。Compared with the traditional artificial neural network,pulse neural network has the advantages of hardware-friendliness and low energy consumption.Compared with the electric pulse neural network,the photon pulse neural network has the advantages of high speed,low energy consumption,large transmission capacity and strong anti-electromagnetic interference ability.Based on the semiconductor optical amplifier(SOA),a new neuron model of photon pulse—LIF(leakage integration and fire)model is designed in this paper,and the application of LIF model in digital logic is explored.The“XOR”logic function based on the model is realized,and an excitatory and inhibitory neuron is improved,LIF model,XOR logic and good output of excitatory and inhibitory neurons were obtained by optical communication simulation software.
