摘要：
In this paper, the third-harmonic generation (THG) in GaAs/Ga1-xAlxAs ridge quantum wires is studied in detail. An analytic expression for the THG is obtained using a compact density matrix approach and an iterative procedure. Numerical calculations are performed for the typical GaAs/Ga1-xAlxAs ridge quantum wire. The results show that the maximum THG over 10(-9)?m(2)?/V-2? can be obtained. Another important point is that the structural parameters have great influence on the THG in this system. (C) 2011 Elsevier B.V. All rights reserved.
