Abstract
Mass-transport and conventional burying techniques were combined to fabricate narrow active stripe lasers. Lowest threshold current of 9. 6 mA was obtained under cw operation for the active layer width of 1 mu m in 1. 5 mu m wavelength region. The maximum light output power and differential quantum efficiency were 10. 6 mw and 17 percent/ facet, respectively. With this structure, complete single transverse mode operation was achieved both for Fabry-Perot (FP) type and bundle-integrated-guide distributed Bragg reflector (BIG-DBR) type lasers.
