Due to some unique advantages such as low threshold current, enhanced polarization stability and polarization controllability, spin vertical-cavity surface-emitting lasers (VCSELs) offer attractive application prospects in optical information technology. At present, related investigations mainly focus on short wavelength spin VCSELs. However, for long wavelength spin VCSELs, some key techniques and problems such as optimal design and fabrication, polarization nonlinear dynamics and their applications, are yet to be solved. Therefore, it is very important to conduct a systematic investigation emphatically on polarization nonlinear dynamics and optimal design of long wavelength spin VCSELs. Firstly, based on experimental investigations of the polarization nonlinear dynamics, the detailed evolution and distribution maps of representative dynamical behaviors can be specified in the representative system parameter spaces. Then reasonable theoretical model will be constructed to describe the polarization nonlinear dynamics of long wavelength spin VCSELs. By carrying on this project, we hope to achieve some breakthroughs in the basic research of long wavelength spin VCSELs, which will afford some theoretical supports for the optimized design of long wavelength spin VCSELs and some core technological supports for the development and application of spin VCSELs in related important fields.
