中文摘要 AI 辅助

我们提出一种精确的代数架构,利用双模($2 \times 2$)线性光学电路评估任意有限傅里叶级数,其中唯一可调组件是编码函数参数的单模移相器。我们证明对于每个傅里叶级数必定存在这样的电路,并基于谱分解推导出其构造的解析方法。所得光学系统对于$N$次谐波展开具有$\mathcal{O}(N)$深度,在无源光学飞行时间内执行函数评估。最后,我们通过数值验证,证明即使对于包含数千个傅里叶项的序列,我们提出的电路构造也能正确合成连续和非连续非线性函数。因此,我们的架构为集成光子平台上的单变量非线性光学计算提供了通用、确定性的基础。

英文摘要

We introduce an exact algebraic architecture that evaluates an arbitrary finite Fourier series using a two-mode ($2 \times 2$) linear optical circuit, with the only tunable components being single-mode phase shifters encoding the function argument. We prove that such a circuit must exist for every Fourier series and derive an analytical method for its construction based on spectral factorisation. The resulting optical system exhibits an $\mathcal{O}(N)$ depth for an $N$-harmonic expansion, executing function evaluations in the passive optical time-of-flight. Finally, we validate our claims numerically, demonstrating that even for sequences with thousands of Fourier terms, our proposed circuit construction correctly synthesises continuous and discontinuous nonlinear functions. Our architecture thus provides a universal, deterministic foundation for single-variable nonlinear optical computing on integrated photonic platforms.
