We theoretically investigate efficient third-harmonic generation (THG) in the heterostructure with a one-dimensional photonic crystal (PC) and a thick metal film. There are both the fundamental Tamm plasmon mode and the high-order mode in the heterostructure. Commonly these two Tamm plasmon modes just satisfy single-resonance condition, but the double-resonance condition can be fulfilled by using a binary PC in the heterostructure. Taking advantage of the tunneling effect of Tamm plasmon modes, THG in the single-resonance heterostructure is enhanced over 3 orders of magnitude more than that in the single metal film, and that in the double-resonance one is further enhanced nearly 2 orders of magnitude.
我们从理论上研究了具有一维光子晶体（PC）和厚金属膜的异质结构中的高效三次谐波产生（THG）。在异质结构中存在基态 Tamm 等离子体模和高阶模。通常，这两种 Tamm 等离子体模仅满足单共振条件，但通过在异质结构中使用二进制 PC 可以满足双共振条件。利用 Tamm 等离子体模的隧道效应，单共振异质结构中的 THG 增强超过 3 个数量级，比单金属膜中的增强还要高，而双共振异质结构中的增强则进一步提高了近 2 个数量级。
