Abstract

This paper presents strongly improved results from optimized surface emitting laser diodes, which are based on a surface mode emission (SME) technique. This technique can be applied to conventional horizontal cavity laser diodes to achieve an efficient surface emission with low beam divergence as well as a quasi-single-mode operation. It is based on a coupling process between the laser mode and a TE0-surface mode propagating in a waveguide structure on top of the laser diode. The intensity emitted per solid angle via the surface into the single beam is more than 10 times higher than the edge emitted intensity per solid angle, which demonstrates the high efficiency of the SME-technique.
