A method of complex analysis of the double-heterostructure stripe-geometry laser, based on a new static model, is presented. The optical field distribution in the active region of the laser is described by the wave equation. The interaction between the optical field and free-charge carriers is expressed by the set of rate equations describing also the carrier-concentration profile. Owing to the interaction, it is necessary to solve these equations by a self-consistent procedure. The results of the analysis are light-current characteristics, current dependences of a modal gain, spectra and a near-field pattern. These characteristics are demonstrated in an example.
