Paper Abstract

We present the preliminary results of investigations of influence of the finiteness of device aperture, axial magnetic field and external feedback mirror on the transverse structure of emission of a broad-area VCSEL. We use the model developed in our recent works which takes into account the spatially dependent reflection from DBR mirrors of a VCSEL. It is shown that boundary conditions can freeze a temporal dynamics of long wavelength instabilities which are presented in an unbounded device. The external feedback changes relative threshold of polarized spatial Fourier modes. A presence of axial magnetic field only slightly increases polarization degree of patterns arising near the laser threshold.
