We demonstrate that confined Tamm plasmon modes can be advantageously exploited for the realization of new kind of metal/semiconductor lasers. Laser emission is demonstrated for Tamm structures with various diameters of the metallic disks which provide the confinement. A reduction of the threshold with the size is observed. The competition between the acceleration of the spontaneous emission and the increase of the losses leads to an optimal size, which is in good agreement with calculations.
我们证明，受限的 Tamm 等离子体模式可以被有利地利用来实现新型的金属/半导体激光器。对于具有不同金属盘直径的 Tamm 结构，我们演示了激光发射，这些金属盘提供了限制。随着尺寸的减小，阈值降低。自发发射的加速和损耗的增加之间的竞争导致了最佳尺寸，这与计算结果非常吻合。
