摘要

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-(mu)m-long devices was as low as 24 mA, with a maximal single facet output power of 4.2 mW at 15 deg C. Longer devices achieved a maximal single facet output power as high as 12.7 mW, a single facet slope efficiency of 8.4percent, and a lasing threshold current density of 1 kA/cm~(2). Continuous wave laser operation was obtained up to 45 deg 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.
