AI 中文摘要
我们利用具有模拟非对称损耗分布的线性增长有效折射率波导阵列，研究N=1和N=2光子N00N态的布洛赫振荡。以等概率输入N=1和N=2 N00N态，在半布洛赫周期附近抽取部分波导，选择性输出特定光子数态。通过调节输入相位，我们实现了以双光子为主（输出占比80%）和以单光子为主（输出占比90%）的动态切换，为计算和网络用光子电路中改进态制备提供了途径。
英文摘要
We explore Bloch oscillations of $N=1$ and $N=2$ photonic N00N states, using an array of linearly growing effective index waveguides with a simulated asymmetric loss profile. Starting with equal probability input $N=1$ and $N=2$ N00N states, and siphoning off a portion of the waveguides near the half Bloch period, we selectively output specific photon number states. Tuning the input phase, we achieve dynamic switching between 2-photon dominated (80\% of the output) and 1-photon dominated (90\% of the output) cases. This offers a path to improved state preparation in photonic circuits used in computing and networking.
