In this paper, we present high-power tapered diodes as Fabry-Perot lasers and as amplifiers in narrow-linewidth operation within an external cavity. In section 2 we review design considerations for the device design as well as for the fabrication process. From basic broad-area and ridge-waveguide designs, internal parameters are derived (section 3) which are implemented in BPM simulations for taper device optimization. Section 4 gives an overview of our results on tapered diode lasers, section 5 finally the results on tapered amplifiers operated as gain medium in an external cavity setup
