Abstract

In order to enhance current Injection efficiency of Y-groove inner strife(VIS) quantum wire lasers, three different current configurations, n-blocking on p-substrate(VIPS), p-n-p-n blocking on n-substrate(VI(PN)nS), p-blocking on n-substrate(VINS) have been designed and fabricated. Among them VIPS laser showed the most stable characteristics of lasing up to 5 mW/facet, a threshold current of 39.9 mA at 818 nm, and an external differential quantum efficiency of 24 %/facet. The current tuning rate was almost linear 0.031 nm/mA, and the temperature tuning rate was measured to be 0.14 nm/$^{\circ}C$.
