| Popis: | We discuss the fabrication process and characteristics of three consecutive runs of double-fused 1.5-μm vertical- cavity lasers. We have measured light-current characteristics of over three hundred lasers with ten different diameters between 6 and 60 μm and observe a yield of over 95%. The process and design improvements resulted in a low pulsed threshold current of 3 mA on a number of 6- and 8-μm-diameter devices and threshold current density of 2 kA cm−2 on 60-μm-diameter devices at room temperature. |
