Abstract :
A V-channel substrate inner stripe diode laser with conventional cleaved facet mirrors has been modified by micro-machining with a focused ion beam to produce a smooth machined output mirror with no change in its lasing threshold and only a small decrease in its external differential quantum efficiency.
