Secondary pulsations are firstly analysed by using a model where a modal expansion of the electric field is performed. The maximum power of the secondary pulsations and the time at which they appear fluctuate when the spontaneous emission noise is present. A linear relation between the two previous quantities for each individual turn-off event is found. In the single-mode regime, the averaged maximum power during turn-off transients increases when increasing the injection current. However, in the multi-mode regime, the strength of secondary pulsations decreases when increasing the current. Secondary pulsations are also analysed by using a spatio-temporal description of the VCSEL dynamics, where the modal profiles are determined from the distribution of injected carriers and the thermal lens. This model also incorporates polarization effects and a frequency-dependent susceptibility. In this model, the carrier-induced refractive index changes increase the strength of secondary pulsations as compared to that obtained with the modal expansion. It is also shown that the use of ring-shaped electrical contact enhances the strength of secondary pulsations, while it decreases when multi-transverse mode operation is present.Financial support has been provided by CICYT (Spain) Project T1C99-0645 and by EC Human Potential Research Training Network VISTA (HPRN CT-2000-00034).Peer reviewedThe International Society for Optics and Photonics200920092002info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_65012373 bytes330622 bytes43785 bytestext/plainapplication/octet-streamapplication/x-texhttp://hdl.handle.net/10261/18029reponame:DIGITAL.CSIC.
