Lateral-mode analysis of gain-guided and index-guided semiconductor-laser arrays.

Presents an analysis of the lateral-mode behavior of a semiconductor-laser array after including the effect of injected charge carriers on the active-layer dielectric constant. Effect of an index profile that peaks at the center of the emitter where the gain is maximum on the behavior of a gain-guided array; Features of phase-locked index-guided arrays; Evaluation of the coupling coefficients.
