Very high single lateral mode output powers of 650 mW are obtained from a diode laser with a unique waveguide design. The waveguide flares in the lateral dimension to create a larger spot size on the facet and simultaneously tapers in the transverse

Utilizing separate structures for the lateral confinement of the optical mode and injected carriers, we optimize the overlap of the optical mode with the gain to demonstrate lasers with lower threshold currents than standard ridge waveguide lasers.

We demonstrate a new concept for stabilizing the lateral mode in narrow stripe diode lasers that enables the laser to be driven to twice the current density of conventional lasers of similar design without beam instability.
