If the indices n(II), n(I,III) of the regions, the thickness 2a of the active region (AR) and the wavelength A for a single symmetric step-index quantum well laser (SSSIQWL) are given, the normalized propagation constant (NPC) a is obtained. In this novel method, absorption and gain coefficients for the SSSIQWL have been obtained in terms of the NPCs alpha in the even and odd fields, directly.
