神经形态光子学最近重新受到关注，这一领域有望触及机器智能的关键且尚未被探索的领域。在孤立神经元和模拟互连方面已经取得了进展；然而，这种重新兴起尚未产生能够与其他类似神经元相互作用的硅光子神经元的演示。我们报道了一种在常规硅光子工艺线上制造的调制器类光子神经元。我们展示了传递函数可配置性、扇入、抑制、时间分辨处理，以及至关重要的自突触级联性等行为——这些行为足以使一个器件作为神经元参与到类似神经元网络中。硅光子调制器神经元构成了在当前可用的硅光子平台上完全集成光子神经网络所需的最后一块拼图。
There has been a recently renewed interest in neuromorphic photonics, a field promising to access pivotal and unexplored regimes of machine intelligence. Progress has been made on isolated neurons and analog interconnects; nevertheless, this renewal has yet to produce a demonstration of a silicon photonic neuron capable of interacting with other like neurons. We report a modulator-class photonic neuron fabricated in a conventional silicon photonic process line. We demonstrate behaviors of transfer function configurability, fan-in, inhibition, time-resolved processing, and, crucially, autaptic cascadability -- a sufficient set of behaviors for a device to act as a neuron participating in a network of like neurons. The silicon photonic modulator neuron constitutes the final piece needed to make photonic neural networks fully integrated on currently available silicon photonic platforms.
