Multiparameter optimization of optical nonlinearities in semiconductor quantum wells by supersymmetric quantum mechanics

摘要

The multiparameter procedure of semiconductor quantum well profile optimization, using the supersymmetric quantum mechanics, is described and explored, The method generates families of isospectral potentials that depend on a specified number of scalar parameters, which are then varied so to maximize the desired property of the system, in this case the nonlinear susceptibility chi ((2))(0) which gives rise to the optical rectification. The merits and limits of the multiparameter procedure are discussed. (C) 2001 Elsevier Science B.V. All rights reserved. [References: 5]
