Abstract(in English) | Semiconductor membrane laser, which consists of a high-ondex contrast waveguide, is very promising for low power light sources with very short cavity length due to an enhanced modal gain. We have fabricated a lateral current injection (LCI) p-i-n structure with a thin GaInAsP core layer on a semi insulating substrate for injection type membrane laser, however the device characteristics were not satisfactory to realize high performance operation based on high-index contrast waveguides. In this paper, we report improved lasing characteristics, ie. an increase of the internal quantum efficiency, reduced threshold current density, and increased differential quantum efficiency. A room-temperature (RT) continuous wave (CW) operation with a threshold current of 11 mA, which corresponds to a threshold current density of 0.9 kA/cm^2, was obtained for a 1.7 μm stripe width and 730 μm long Fabry-Perot (F.P.) cavity laser. |
