Paper Abstract

A simple one-dimensional theory predicts mode selective properties of a semiconductor laser structure consisting of several equally long elements which are separated by regions with different effective refractive index and gain. Measurements on realized lasers with etched and unpumped regions interrupting a ridge waveguide confirm this theory. The best laser shows a side mode suppression of about 25 dB at 1.5xIth and maintains single mode operation under high speed direct modulation.
