A new method for high-speed photonic arbitrary waveform generation using optical sinc-pulse sequences and Mach-Zehnder modulators is presented, enabling a three- to four-fold increase in sampling rate compared to the bandwidth of the used modulator for generating the pulses and an $N$ -fold increase compared to the bandwidth of the incorporated electronics, with $N$ as the number of parallel branches. Proof of concept experimental results, using conventional off-the-shelf fiber components have been presented in this study. Due to its simplicity and the possibility to achieve high sampling rates with low bandwidth photonic and electronic equipment, this method is beneficial for integration on a silicon photonics platform.

光子任意波形生成,采样率是调制器带宽的三倍

提出了一种使用光学正弦脉冲序列和 Mach-Zehnder 调制器生成高速光子任意波形的新方法,与用于生成脉冲和脉冲的调制器的带宽相比,采样率提高了三到四倍。一个 $N$ - 与集成电子设备的带宽相比增加了倍, $N$ 作为并行分支的数量。本研究中提供了使用传统现成纤维组件的概念实验结果证明。由于其简单性和使用低带宽光子和电子设备实现高采样率的可能性,这种方法有利于集成在硅光子学平台上。
