Dissipative localized structures exhibit intricate bifurcation diagrams. An adequate theory has been developed in one space dimension; however, discrepancies arise with the experiments. Based on an optical feedback with spatially modulated input beam, we set up a 1D forced configuration in a nematic liquid crystal layer. We characterize experimentally and theoretically the homoclinic snaking diagram of localized patterns, providing a reconciliation between theory and experiments.
耗散局域结构表现出复杂的分岔图。在一维空间中已经发展出了一个合适的理论；然而，与实验结果存在差异。基于具有空间调制输入光束的光反馈，我们在向列相液晶层中建立了一维强迫配置。我们从实验和理论上对局域模式的同宿蛇形图进行了特征描述，为理论和实验之间提供了一致性。
