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.
