摘要

在这项工作中,我们对基于高度非线性波导中的四波混合效应的光子非常规加速器进行了数值分析。所提出的方案可以直接在光域中充当非线性信号处理的全模拟系统。通过利用丰富的凯尔诱导非线性,可以生成输入信号的多种非线性变换,并用于解决复杂的非线性任务。我们首先评估了我们的方案在 Santa-Fe 混沌时间序列预测中的性能。在光通信场景中的全光非线性补偿中,我们揭示了这一处理器的真正威力,其结果优于强大的机器学习算法,同时降低了功耗和计算复杂度。最后,我们展示了如何将 FWM 模块用作可重新配置的非线性激活模块,使其能够再现特征函数,如 sigmoid 或整流线性单元。

Unconventional Computing Based on Four Wave Mixing in Highly Nonlinear Waveguides
In this work we numerically analyze a photonic unconventional accelerator based on the four-wave mixing effect in highly nonlinear waveguides. The proposed scheme can act as a fully analogue system for nonlinear signal processing directly in the optical domain. By exploiting the rich Kerr-induced nonlinearities, multiple nonlinear transformations of an input signal can be generated and used for solving complex nonlinear tasks. We first evaluate the performance of our scheme in the Santa-Fe chaotic time-series prediction. The true power of this processor is revealed in the all-optical nonlinearity compensation in an optical communication scenario where we provide results superior to those offered by strong machine learning algorithms with reduced power consumption and computational complexity. Finally, we showcase how the FWM module can be used as a reconfigurable nonlinear activation module being capable of reproducing characteristic functions such as sigmoid or rectified linear unit.

期刊介绍: The IEEE Journal of Quantum Electronics is dedicated to the publication of manuscripts reporting novel experimental or theoretical results in the broad field of the science and technology of quantum electronics. The Journal comprises original contributions, both regular papers and letters, describing significant advances in the understanding of quantum electronics phenomena or the demonstration of new devices, systems, or applications. Manuscripts reporting new developments in systems and applications must emphasize quantum electronics principles or devices. The scope of JQE encompasses the generation, propagation, detection, and application of coherent electromagnetic radiation having wavelengths below one millimeter (i.e., in the submillimeter, infrared, visible, ultraviolet, etc., regions). Whether the focus of a manuscript is a quantum-electronic device or phenomenon, the critical factor in the editorial review of a manuscript is the potential impact of the results presented on continuing research in the field or on advancing the technological base of quantum electronics.
