Paper Abstract

A new method of additional transverse mode selection in high- power broad-waveguide separate confinement heterostructure quantum-well lasers by means of facet inclination is proposed. Theoretical investigation of mode selection and numerical calculations for GaAs-AlGaAs BW-SCH-QW laser with inclined facet with wavelength 860 nm and wide range of waveguide width has been carried out. The possibility of reducing power density on the mirror keeping single-mode generation and thus increasing fundamental mode output power 1.2 times is shown.
