The optical Darboux transformer for solitons is introduced as a photonic device that performs the Darboux transformation directly in the optical domain. This enables two major advances for optical signal processing based on the nonlinear Fourier transform: (i) the multiplexing of solitonic waveforms corresponding to different discrete eigenvalues of the Zakharov-Shabat system, and (ii) the selective filtering of an arbitrary number of individual solitons too. The optical Darboux transformer can be built using existing commercially available photonic technology components and constitutes a universal tool for signal processing, optical communications, optical rogue waves generation, and waveform shaping and control in the nonlinear Fourier domain.
用于孤子的光学达布变换装置被引入作为一种能在光学域直接执行达布变换的光子器件。这为基于非线性傅里叶变换的光信号处理带来了两大进展：（i）对应于扎哈罗夫 - 沙巴特系统不同离散本征值的孤子波形复用，以及（ii）对任意数量单个孤子的选择性滤波。光学达布变换装置可以使用现有的商用光子技术组件构建，并且构成了用于信号处理、光通信、光学 rogue 波生成以及非线性傅里叶域中的波形整形与控制的通用工具。
