A quasi-analytic model for longitudinally non-uniform semiconductor optical sources

This paper presents a new, efficient and compact method to solve the self-consistent model for semiconductor optical sources that admit longitudinally slowly varying (adiabatic) field solutions. Both the optical field and the carrier equations are computed by a function expansion technique using the Hermite-Gauss functions as the basis set. Results obtained by the proposed method are shown to agree favourably with those from other numerical methods. (C) 2000 Elsevier Science B.V. All rights reserved.
