Abstract: The method used for measuring the near-field light intensity profiles, radiative intensity line width and equi-amplitude contour areas in the radiative region, is introduced. For devices with different stripe geometries, the change of light emitting width and area, far-field light intensity patterns and light intensity topograph, as a function of the injection current is analysed. -
