Abstract
We present a novel concept to achieve surface emission from convention al semiconductor laser diodes. This new type of laser diode is modifie d to allow a coupling of the laser mode to a transverse electric polar ized surface mode. As a result we achieve surface emission from GaAs/A lGaAs double heterostructure laser diodes with a beam divergence of 0. 2%. This novel concept has a high potential for the realization of a b eam steering device.
