Abstract

We present a theoretical and experimental research of the linewidth enhancement factor or α factor in multiple-longitudinal mode semiconductor lasers. In this work, several methods originally developed for single-mode lasers have been adapted for their use with multiple-longitudinal mode lasers and applied to each mode of several Fabry-Perot lasers at a time. The concepts of material LEF and device LEF are compared and discussed.
