摘要：

The polarization competition in vertical cavity surface-emitting lasers with two nearly degenerate modes is analyzed with the aim of studying their noise properties and, in particular, amplitude fluctuations and spectral linewidth. The coupling between the two modes is attributed to carriers, different spin populations, and structural anisotropies, including the consequences of the electro-optic effect that results from current injection. The model is based on quantum equations of motion with Langevin noise sources. Results for the noise spectra in the regions where mode competition is stronger are reported and discussed.
