Abstract
A novel surface emitting laser diode beam steering device based on the excitation and emission of surface modes is presented. This new device is a longitudinally segmented wavelength tunable GaAs/AlGaAs double heterostructure laser diode, which is modified to allow a coupling of the laser mode to a transverse electric polarized surface mode. This results in surface emission with very narrow beam divergence. A steering of the surface emitted farfield pattern is achieved by a variation of the emission wavelength: By electrically changing the emission wavelength from 877.54 nm to 879.13 nm the dominant surface emitted peak is steered by 0.4°.
