Abstract
A mode-expansion laser that can be fabricated by standard buried heter ostructure laser processes without introducing any extra complex proce ssing steps is demonstrated. With the diluted waveguide structure, the originally strongly guided laser mode can be expanded and better matc hed to the weakly guided fibre mode. Both the coupling efficiency and laser-to-fibre alignment tolerance are improved. Such a laser structur e has a great potential to reduce the cost of laser diode modules.
