本文研究了GaAs量子威尔斯阱中由束缚态到准束缚态的子带间跃迁引起的真空场拉比分裂。设计了一种波导，并利用棱镜技术将红外光共振耦合到波导中。反射和光电流谱显示尖锐的拉比双峰。研究了这种结构的红外探测率随温度的变化。我们证明了真空场拉比分裂的子带间吸收是容易观察到的，并在光电子器件中有潜在的应用。
The vacuum-field Rabi splitting due to bound-to-quasibound intersubband transitions in GaAs quantum wells has been demonstrated. A waveguide was designed and the infrared light was resonantly coupled inside with a prismlike technique. Reflection and photocurrent spectra show sharp Rabi doublets. The infrared detectivity of such a structure was investigated with temperature. We have proved that the vacuum-field Rabi splitting of intersubband absorption is easy to observe and has potential applications in optoelectronic devices.
