Abstract :
Summary form only given. Tapered semiconductor amplifiers have successfully demonstrated high-power diffraction-limited emission. So far, all these amplifiers had normal incidence facets coated with antireflection (AR) coating to prevent self-oscillation. In this work, an angled-facet high-power diffraction-limited tapered GaAs-AlGaAs QW semiconductor amplifier operating at 809-nm was realized. Due to the angled facet structure, any residual reflection from the facets is fed back at a small angle with the signal propagation direction
