An injection-type distributed-feedback laser, with wirelike active regions, directly bonded on a silicon-on-insulator substrate, was realized. A low threshold current Ith of 104 mA was obtained at a stripe width of 25 mum and a cavity length of 1 mm. A sidemode suppression ratio of 28 dB was obtained at 1.3 Ith.
1540 nm wavelength GaInAsP/InP quantum-wire (24 nm wide) distributed feedback lasers were realized by dry etching and regrowth method. A threshold current as low as 2.7 mA, a differential quantum efficiency of 19 %/facet and an SMSR of 51 dB (@ 2Ith) were attained under RT-CW condition for the stripe width of 3.0 mum and the cavity length of 330 mum
