摘要：

We present a theoretical investigation of two longitudinal mode microelectromechanical system (MEMS)-tunable vertical-cavity surface-emitting laser (VCSEL). The spatio-temporal dynamics of semiconductor laser with particular focus on the parameters relevant for THz photomixing is studied. A four-level model which allows for the polarization of the laser field by including the spin sublevels of the conduction and valence bands of a semiconductor is introduced. The maximum obtained wavelength separation between modes is 30 nm which corresponds to 3.77 THz in frequency range.
