论文摘要
广泛的文献表明，在不同的物理参数（例如，确保平面响应和/或对制造误差的容忍度）的变化下，有限的脉冲响应（FIR）干涉仪可以设计为不敏感。在这种情况下，我将展示Bloch Sphere表示如何成为一种非常强大的设计工具，可以为自动校正设备（例如宽带50:50拆分器或扁平交叉破坏者）的工作原理提供卓越的物理见解，因此可以通过简单的分析公式设计。我最终将回顾一下VTT的微米级硅光子学平台中自相关设计实施的最新进展。
Extensive literature has shown that finite impulse response (FIR) interferometers can be engineered to be insensitive under variations of different physical parameters, e.g., to ensure flat-top response and/or tolerance to fabrication errors. In this context, I will show how the Bloch sphere representation can be a very powerful design tool providing superior physical insight into the working principle of autocorrective devices like broadband 50:50 splitters or flat-top interleavers, that can be therefore designed through simple analytical formulas. I will eventually review the recent progress in practical implementation of the autocorrective designs in the micron-scale silicon photonics platform of VTT.
