  • Abstract
    The authors have successfully demonstrated 1×4 MMI array laser diode which is locked in phase achieving power in excess of 400 mW from a single mode output waveguide with slope efficiency of 20 % per facet. Far field measured at FWHM being 16.1° at 418 mW and remained single lobed as the drive current was increased. This is an improvement over using single ridge waveguide by a factor of three when the same active length is used.
