Abstract A theory analysis of the four-wave mixing (FWM) scheme in a double asymmetry quantum dots (QDs) system is performed. The efficiency of the generated field decreases in an oscillating mode for the penetration depth and is significantly enhanced because of three-wave mixing (TWM). The dependence of the conversion efficiency on the three coupling laser fields and decay rate is also discussed. High conversion efficiency up to 0.8 is demonstrated with small propagation length at low temperature. Such a solid-state system may be more practical due to the flexibility of QDs to generate coherent short-wavelength radiation.
