Abstract :
Summary form only given. We report direct measurement of the scattered field intensity from oxide-confinement aperture VCSELs. The devices in this experiment consist of 960-nm wavelength-matched AlGaAs laser cavities sandwiched between two oxide layers with rectangular apertures. Although each device operates in a single longitudinal mode, the number of transverse modes typically varies between one and six, depending on drive current.
