Abstract:
A broad area semiconductor diode laser device includes a multiple flared oscillator waveguide including a plurality of component flared oscillator waveguides, each component flared oscillator waveguide including a multimode high reflector facet, a partial reflector facet spaced apart from the high reflector facet, and a flared current injection region extending and widening between the multimode high reflector facet and the partial reflector facet, wherein the ratio of a partial reflector facet width to a high reflector facet width is n:1, where n>1, and wherein the component flared oscillator waveguides of the multiple flared oscillator waveguide are arranged in a row such that portions of the flared current injection regions of adjacently situated component flared oscillator waveguides overlap each other or are in proximity to each other on the order of the wavelength of light emitted by the component flared oscillator waveguides.
