摘要

在任何神经网络的光学实现中,一个关键因素是非线性神经元。该设备最常见的特性是对激活输入的饱和响应。激活输入是通过互连网络路由到神经元的所有入射光束的加权和。我们报道了在光折变晶体中使用场屏蔽效应的非线性神经元,该晶体执行入射强度的非相干添加1,2。该装置以各种饱和、阈值或双向方式响应连续波或同步脉冲输入。利用光折变CdTe:In,我们展示了对抑制和兴奋输入的响应,对1.0-1.4 μm范围内的入射光具有高灵敏度。

Nonlinear Neurons Using the Fieldshielding Effect in Photorefractive CdTe
A key element in the optical implementation of any neural network is the nonlinear neuron. The most common required feature of this device is a saturating response to an activation input. The activation input is the weighted sum of all the incident beams which are routed through an interconnection network to the neuron. We report on nonlinear neurons using the fieldshielding effect in photorefractive crystals which perform an incoherent addition of the incident intensities1,2. The device responds to CW or synchronously pulsed inputs in a variety of saturated, thresholded or bidirectional manners. Using photorefractive CdTe:In, we demonstrate a response to both inhibitory and excitatory inputs with a high sensitivity to incident light in the 1.0-1.4 μm range.
