Paper Abstract

First results from surface mode emitting (SME)-laser diodes utilizing a first-order grating are presented. The use of a first-order grating instead of a third-order grating strongly improves the radiation characteristics of surface emitting SME-laser diodes. Although a real single mode operation from SME-laser diodes is not yet achieved, the tunability of the main emission wavelength by changes of the waveguide thickness is clearly demonstrated. The crucial feature of the SME-technique is that it provides a high flexibility, when processing surface emitting laser diodes with desired radiation pattern and wavelength emission characteristics. These features are discussed to demonstrate the high application potential of the SME-laser diodes.
