We present a new scheme to investigate the efficient propagation of the generated four-wave mixing field (FWM) and spatially dependent structured transparency in a semiconductor quantum-dots (SQDs) structure. Here, we discuss the efficient propagation of the generated FWM field in both homogeneous and inhomogeneous media and find that as the optical length increases, efficiency decreases rapidly in the inhomogeneous medium than in the homogeneous medium. The generated FWM field has a high conversion efficiency of approximately 
at 
m and 
, and show a strong dependency on the driving control field. Furthermore, we observe distinct spatially dependent structure beams created by the quantum interference phenomenon of the superposition of two Laguerre-Gaussian (LG) fields that carries orbital angular momentum (OAM). It is notice that the absorption profile of the probe field exhibits l-fold symmetry irrespective of whether both OAM numbers have equal (
) or distinct (
) values. Along with the various applications of AOM in various domains, our findings may be useful in the practical application of quantum information processing.
