In this way the effective mass approximation is used to calculate the electronic wave function and energies numerically. Density matrix approach in addition with iterative method is used to obtain the (linear and third order nonlinear) change in the refractive indices (RI) and absorption coefficient(AC) analytically. The effect of size, magnetic field and the interface width are investigated. It is found that nonlinear parts of RI and RA have large contribution and must be considered in calculation of the total RI and RA. }, URL = {http://opsi.ir/article-1-241-en.html}, eprint = {http://opsi.ir/article-1-241-en.pdf}, journal = {Accepted and Presented Articles of OPSI Conferences}, doi = {}, year = {2014} }
