High power, buried heterostructure laser with flared waveguide horns have been grown by a two-step metalorganic chemical vapor deposition process. Powers up to 120 mW cw in a single longitudinal and transverse mode have been obtained from a single stripe laser. The flared waveguides decrease the lateral far-field divergence from 25° to 11° while supporting only the lowest order transverse mode.
