Hybrid Si/III–V, Fabry–Perot evanescent lasers are demonstrated, utilizing InGaAsP as the III–V gain material for the first time to our knowledge. The lasing threshold current of 300 - μ m -long devices was as low as 24 mA , with a maximal single facet output power of 4.2 mW at 15 ° C . Longer devices achieved a maximal single facet output power as high as 12.7 mW , a single facet slope efficiency of 8.4%, and a lasing threshold current density of 1 kA cm 2 . Continuous wave laser operation was obtained up to 45 ° C . The threshold current density, output power, and efficiency obtained improve upon those of previously reported devices having a similar geometry. Facet images indicate that the output light is largely confined to the Si waveguide.
