The optical response of the intersubband excitation of multiple two-dimensional electron gases within a semiconductor microcavity has been studied through angle-dependent reflectance measurements. Using a resonator based on total internal reflection, a clear splitting of about 14 meV of the coupled intersubband cavity modes is observed from 10 K to room temperature, with resulting polaritonlike dispersion. The experimental findings are in good agreement with theoretical calculations performed in a transfer-matrix formalism.
通过角度相关反射率测量，研究了半导体微腔内多个二维电子气的子带间激发的光学响应。使用基于全内反射的谐振器，在10K至室温范围内观察到耦合子带间腔模有明显约14meV的分裂，并产生类似极化激元的色散。实验结果与用转移矩阵形式进行的理论计算吻合良好。
