Analysis of the dynamics of a blue-violet Inx Ga1-x N laser with a saturable absorber.

Tronciu, V. Z. and Yamada, M. and Abram, R. A. (2004) 'Analysis of the dynamics of a blue-violet Inx Ga1-x N laser with a saturable absorber.', Physical review E., 70 (2). 026604.

Abstract

We report the results of numerical investigations of the dynamical behavior of a blue-violet InGaN laser with a specially incorporated saturable absorber. We have identified the nature of the bifurcation that occurs in the device dynamics and also the conditions that are necessary for self-pulsating and excitable operations. We also demonstrate the influence of the relevant device parameters on the laser dynamics and show how the properties of the saturable absorber and its position in the device have a considerable influence on the laser behavior. Finally theoretical investigations of the excitable behavior and a confirmation of the excitability properties of an InGaN laser are presented and discussed.
