摘要:

基于光子延迟的水库计算(RC)最近获得了相当大的关注,因为它允许简单的技术实现的RC概念,可以在高速运行。在本文中,我们讨论了一个实用的,紧凑的和强大的实现光子延迟基于RC,通过集成激光器和5.4厘米的延迟线的InP光子集成电路。我们演示了该芯片的操作与23个节点的速度为0.87GSa/s,表现出类似于以前的非集成的基于延迟的设置。我们还研究了其他两种后处理方法,以获得更多的节点在输出层。我们表明,这些方法大大提高了性能,而不影响计算速度。

英文摘要:

Photonic delay-based reservoir computing (RC) has gained considerable attention lately, as it allows for simple technological implementations of the RC concept that can operate at high speed. In this paper, we discuss a practical, compact and robust implementation of photonic delay-based RC, by integrating a laser and a 5.4cm delay line on an InP photonic integrated circuit. We demonstrate the operation of this chip with 23 nodes at a speed of 0.87GSa/s, showing performances that are similar to previous non-integrated delay-based setups. We also investigate two other post-processing methods to obtain more nodes in the output layer. We show that these methods improve the performance drastically, without compromising the computation speed.
