我们报告了一个广泛的实验研究子带间激发在太赫兹范围内所产生的量子阱和零维金属-金属微腔之间的耦合。由于谐振腔的概念简单，我们得到了一个非常可预测和可控的系统来研究光-物质相互作用。实验数据是通过将量子力学方法与有效的介质电磁模拟相结合来建模的，该模拟允许我们考虑系统的损耗。通过将我们的模型与数据进行比较，我们能够检索微观信息，例如作为温度函数的不同子带上的电子布居。我们的建模方法为子带间光物质耦合系统的设计工具奠定了基础。
We report on an extensive experimental study of intersubband excitations in the THz range arising from the coupling between a quantum well and a zero-dimensional metal-metal microcavities. Because of the conceptual simplicity of the resonators we obtain an extremely predictable and controllable system to investigate light-matter interaction. The experimental data is modelled by combining a quantum mechanical approach with an effective medium electromagnetic simulation that allows us to take into account the losses of the system. By comparing our modelling with the data we are able to retrieve microscopic information, such as the electronic populations on different subbands as a function of the temperature. Our modelling approach sets the base of a designer tool for intersubband light-matter coupled systems.
