英文摘要The inventive III/V semiconductor lasers comprise mode-shaping layers (13, 17) disposed in the upper and lower cladding regions, respectively, and having larger refractive index than the adjoining cladding material. Incorporation of the mode-shaping layers can significantly spread the mode structure of the laser, with attendant reduction of beam spreading. Preferred embodiments are Al-free III/V semiconductor lasers. Especially preferred are such lasers that do not have quaternary III/V semiconductor material between active region and substrate, for improved heat removal.
