Abstract

We report the excitation of optical Tamm states (OTS) in inverse opal (IO) - based three-dimensional photonic crystal on a flat metal substrate, validated through both numerical simulations and experimental observations. Large area, uniform Tamm inverse opal (Tamm-IO) structures were fabricated without the use of any corrosive chemicals. Upon infiltration of non-reactive solvents such as methanol and ethanol into the IO, a noticeable shift of the OTS, consistent with our simulations is observed, and the temporal dynamics of the same have been investigated. The experimentally obtained sensitivity is ∼ 110 nm/RIU which is of the same order as the computed value, making the IO OTS to be an attractive sensing tool.

用于传感应用的反蛋白石光学塔姆态

我们报告了在平面金属基底上基于反蛋白石（IO）的三维光子晶体中激发光学塔姆态（OTS）的情况，并通过数值模拟和实验观察进行了验证。在不使用任何腐蚀性化学品的情况下，制造出了大面积、均匀的反蛋白石（Tamm-IO）结构。当甲醇和乙醇等非反应性溶剂渗入 IO 时，观察到 OTS 发生了明显的偏移，这与我们的模拟结果一致，并对其时间动态进行了研究。实验得出的灵敏度为 110 nm/RIU，与计算值处于同一数量级，这使得 IO OTS 成为一种极具吸引力的传感工具。

期刊介绍： This journal establishes a dedicated channel for physicists, material scientists, chemists, engineers and computer scientists who are interested in photonics and nanostructures, and especially in research related to photonic crystals, photonic band gaps and metamaterials. The Journal sheds light on the latest developments in this growing field of science that will see the emergence of faster telecommunications and ultimately computers that use light instead of electrons to connect components.
