摘要：

We report on the first intersubband-interband doubleresonance experiments in undoped GaAs/AI0.33Ga0.67As multiple quantum well structures at room temperature. The well width is 78 A. A Ti:Sapphire laser is used to pump the interband transitions while the first intersubband transition is probed with a CO2 laser. The intersubband absorption is found to peak at 10.6 μm and a 10 meV linewidth is measured. The absorption signal is also recorded at a fixed CO2 tuning while varying the pump laser wavelength from 700 to 850 nm. A high resolution spectrum is obtained which reflects the steplike density of states with sharp peaks at the exciton resonances. © 1990 IEEE
