Investigation of picosecond-pulse generation by two-section blue-violet semiconductor lasers

Abstract

In this paper, we focus on the generation of ps pulses in a blue-violet InGaN laser containing an additional section (called switching section) with a saturable absorber in axial direction. The main aim of this study is to describe the pulse generation, triggered by injecting a current “Is” into the switching section, theoretically and to explore the dependence of the pulse properties on geometrical and material parameters.
