Abstract(in English) GaInAsP/InP distributed feedback (DFB) lasers consisting of strain-compensated quantum-wire active regions (wire width of 24nm, four-stacked quantum-wires) were realized by electron beam lithography, CH_4/H_2-reactive ion etching and organometallic vapor-phase-epitaxial regrowth for the first time. A threshold current as low as 2.7mA (threshold current density: 270A/cm^2) was attained for the stripe width of 3.0μm and the cavity length of 330μm under the room-temperature continuous-wave condition, which was attributed to a volume effect of the quantum-wire active region and moderately strong reflectivity of the DFB grating. From measurement of the lasing spectrum, single-mode operation with a sub-mode suppression ratio as high as 51dB was observed in the lasing wavelength of 1541nm.
