Abstract
We have fabricated a new GaAlAs/GaAs surface-emitting laser diode with lateral pumping structure. With this structure, the thickness of the active layer can be increased beyond the electron diffusion length, and also both current and light confinement can be incorporated. The lowest threshold current was 180 mA. The far-field pattern shows stable double lobes with an FWHM of 39°. By reducing the size of the mesa, making the wall of the mesa vertical and using the GaAlAs/GaAs quarter-wave stack for the mirror, further improvement can be expected.
