We present a novel concept to achieve surface emission from conventional semiconductor laser diodes. This new type of laser diode is modified to allow a coupling of the laser mode to a transverse electric polarized surface mode. As a result we achieve surface emission from GaAs/AlGaAs double heterostructure laser diodes with a beam divergence of 0.2%. This novel concept has a high potential for the realization of a beam steering device.
