Abstract

Multisection semiconductor lasers with axially nonuniform pumping (Fig. 1) are promising candidates for optoelectronic digital processing devices. In earlier studies,^1–3 coupled rate equations were employed to account for the appearance of hysteresis in current-light output characteristics. Although qualitative explanations were obtained, the predicted hysteresis widths are usually much greater than experimental results.
