我们证明，光致变色分子使开关从弱到超强耦合制度可逆，通过使用全光控制。这种转换是通过光化学诱导分子构象变化来实现的。值得注意的是，拉比分裂700毫电子伏的测量在室温下，对应于32%的分子跃迁能量。在等离子体结构中证明了类似的耦合强度。这样的系统呈现耦合强度和功能能力的独特组合。
We demonstrate that photochromic molecules enable switching from the weak- to ultrastrong-coupling regime reversibly, by using all-optical control. This switch is achieved by photochemically inducing conformational changes in the molecule. Remarkably, a Rabi splitting of 700 meV is measured at room temperature, corresponding to 32% of the molecular transition energy. A similar coupling strength is demonstrated in a plasmonic structure. Such systems present a unique combination of coupling strength and functional capacities.
