摘要：

Graded superlattce quantum cascade lasers ha c shown high operation performance in the mid-infrared. A similar design has been used for terahertz intersubband emission. Narrow band (Deltav - 3 meV) waveguide emission was observed at an energy of 18.8 meV. The energy spectrum was confirmed by magneto-transport measurements. (C) 2002 Elsevier Science B.V.
