Room-temperature continuous-wave operation under optical pumping was demonstrated using GaInAsP/InP membrane distributed feedback (DFB) lasers directly bonded on a silicon-on-insulator (SOI) substrate formed with a rib-waveguide structure. A threshold pump power of 11.3 mW and a submode suppression ratio of 29 dB were obtained for a cavity length of 140 µm and a stripe width of 1.5 µm. Light output was obtained through a 500 µm-long SOI waveguide.
