Paper Abstract

Five-layer AlGaAs double heterostructure injection laser diodes were investigated by measurements of radiation polarization ratios of separate spectrum components and different emitting channels from laser surface. It was found that radiation of the diode is polarized in the plane of the active layer with polarization ratio about 10 percent when pumping currents are sufficiently less of the threshold magnitudes. Polarization ratio of separate spectrum components and an overall radiation increases sharply with the approach to the oscillations lasing threshold and reaches value about 90 percent with conservation of the polarization plane. At the same time the polarization ratio of some radiating channels can decrease sufficiently as the injection current reaches magnitudes above threshold current.
