Abstract

Kink-free, high coupled power of 148 mW into a single mode fiber has been realized by narrowing the vertical beam divergence in 0.98 micrometers laser diodes. It has been found that the high-refractive index GaAs layers have crucial influence on the far field patterns as well as lasing spectrum, since the GaAs is transparent to the emission wavelength of 0.98 micrometers .
