We report the first realization of integrated, all-optical first- and higher-order photonic differentiators operating at terahertz (THz) processing speeds. This is accomplished in a Silicon-on-Insulator (SOI) CMOS-compatible platform using a simple integrated geometry based on (π-)phase-shifted Bragg gratings. Moreover, we achieve on-chip generation of sub-picosecond Hermite-Gaussian pulse waveforms, which are noteworthy for applications in next-generation optical telecommunications.
我们报道了首个以太赫兹（THz）处理速度运行的集成全光一阶及高阶光子微分器的实现。这是在绝缘体上硅（SOI）CMOS兼容平台上，利用基于（π -）相移布拉格光栅的简单集成几何结构完成的。此外，我们实现了片上亚皮秒厄米 - 高斯脉冲波形的生成，这对于下一代光通信应用而言值得关注。
