We have obtained and analyzed optical spectra of a semiconductor slab, containing a quantum well which serves as a source of magnetoexcitons in the presence of an external dc magnetic field. Our setup corresponds to the optical technique based on the breaking of the total internal reflection. Specifically, the semiconductor slab is sandwiched between two external leads/prisms separated from the slab by two gap layers of a dielectric or metal. The reflectivity, transmissivity, and absorption spectra for such a system in a quantizing magnetic field were revealed to display a resonant structure originating from the excitation of electromagnetic modes localized on the semiconductor slab which are strongly coupled with the confined magnetoexcitons. It is surprising that the Rabi splitting for the setup with dielectric gap layers (weak guiding) turns out to be greater than that for metallic and even semiconductor microcavities (strong guiding). Our results were verified by comparing the calculated optical spectra with the dispersion curves for localized modes derived analytically.

半导体平板中弱导波和强导波的激发及其与受限磁激子的强耦合

我们已经获得并分析了半导体板的光谱，其中包含一个量子阱，在存在外部直流磁场的情况下，该量子阱用作磁激子的来源。我们的设置对应于基于打破全内反射的光学技术。具体而言，半导体板夹在两个外部引线/棱镜之间，两个外部引线/棱镜通过电介质或金属的两个间隙层与板隔开。揭示了这种系统在量子化磁场中的反射率、透射率和吸收光谱显示出一种共振结构，该共振结构源自与受限磁激子强耦合的半导体板上的电磁模式的激发。令人惊讶的是，具有介电间隙层（弱引导）的设置的拉比分裂结果大于金属甚至半导体微腔（强引导）的拉比分裂。我们的结果通过将计算的光谱与分析得出的局部模式的色散曲线进行比较来验证。
