我们在均匀介质和光诱导的二维半无限光子晶格之间的界面上展示了表面孤子阵列。这些是非线性的类塔姆表面状态，局部化在一个维度，但周期性地扩展到另一个横向维度。对同相孤子阵列和错相孤子阵列进行了观测，并通过数值模拟验证了实验结果。
We demonstrate surface soliton arrays at the interface between a homogeneous medium and an optically induced two-dimensional semi-infinite photonic lattice. These are nonlinear Tamm-like surface states localized in one but extended periodically in the other transverse dimension. Both in-phase and staggered out-of-phase soliton arrays are observed, and the experimental results are corroborated by numerical simulations.
