Quantum well structure and nonlinear absorption interaction - a review

In this paper, we provide analysis and historical coverage on the topic of quantum well and system utilizing it, the foundational reason for such model, and the physical systems interpretation of such quantum theory. Furthermore, we would like to give an example on the consideration of nonlinear absorption effect in such system, for the example of half-parabolic, asymmetric, finite, additive quantum well with or without the presence of a uniform electric field of perpendicular sectioning in the z-axis. The scope of the origin of quantum well and necessity of such modelling will also be included of typical geometrical configuration of a low-dimensional restrictive well.
