  • Abstract
    The authors report the near-infrared optical activation of inter-subband transitions in a 250 period GaAs/Ga0.75Al0.25As multiple quantum well structure free from intentional doping (undoped). A 0.5% resonant absorption peak around 10.2 mu m has been observed at room temperature under a 320 W/cm2 near-infrared illumination at 0.835 mu m.
