Photonic integrated circuits (PICs) capable of ultra-fast, signal processing are recognized as being fundamental for future applications involving ultra-short optical pulse propagation, including the ability to meet the exponentially growing global fiber-optic telecommunications bandwidth demand. Integrated all-optical signal processors would carry substantial benefits in terms of performance, cost, footprint, and energy efficiency. Here, we demonstrate an optical pulse compressor based on an integrated nonlinear chirper, capable of operating on a sub-picosecond (> 1Tb/s) time scale. It is CMOS compatible and based on a 45cm long, high index doped silica glass waveguide we achieve pulse compression at relatively low input peak powers, due to the high nonlinearity and low linear and nonlinear losses of the device. The flexibility of this platform in terms of nonlinearity and dispersion allows the implementation of several compression schemes.
能够进行超快速信号处理的光子集成电路（PIC）被认为是未来涉及超短光脉冲传播应用的基础，包括满足全球光纤电信带宽呈指数增长的需求的能力。集成全光信号处理器在性能、成本、占地面积和能源效率方面将带来巨大益处。在此，我们展示了一种基于集成非线性啁啾器的光脉冲压缩器，它能够在亚皮秒（>1Tb/s）时间尺度上运行。它与CMOS兼容，基于一根45厘米长、高折射率掺杂石英玻璃波导，由于该器件具有高非线性以及低线性和非线性损耗，我们在相对较低的输入峰值功率下实现了脉冲压缩。该平台在非线性和色散方面的灵活性允许实施多种压缩方案。
