The formation of photonic Bloch oscillations and Wannier-Stark ladders is demonstrated in an exponentially chirped one-dimensional Bragg grating. The photonic Bloch oscillations are investigated using Hamiltonian optics, and direct analogies are made with electron dynamics in periodic potentials. The results of transfer matrix calculations are presented, which show the existence of a photonic Wannier-Stark ladder that should be detectable in experiments.
在指数啁啾的一维布拉格光栅中演示了光子布洛赫振荡和瓦尼尔-斯塔克阶梯的形成。利用哈密顿光学研究了光子布洛赫振荡，并与周期势中的电子动力学进行了直接类比。给出了传输矩阵计算结果，表明存在一个在实验中应可检测到的光子瓦尼尔-斯塔克阶梯。
