We report on experimental observations of homoclinic snaking in a vertical-cavity semiconductor optical amplifier. Our observations in a quasi-one-dimensional and two-dimensional configurations agree qualitatively well with what is expected from recent theoretical and numerical studies. In particular, we show the bifurcation sequence leading to a snaking bifurcation diagram linking single localized states to "localized patterns" or clusters of localized states and demonstrate a parameter region where cluster states are inhibited.
我们报告了垂直腔半导体光放大器中同宿蛇行的实验观测结果。我们在准一维和二维配置中的观测结果与最近的理论和数值研究预期在定性上吻合得很好。特别是，我们展示了导致将单个局域态与“局域模式”或局域态簇相连的蛇行分岔图的分岔序列，并证明了一个抑制簇态的参数区域。
