A GaInAsP/InP buried-heterostructure integrated twin-guide laser with distributed Bragg reflector (BH-DBR-ITG laser) was realized and cw operation was achieved up to 255 K. Single-wavelength operation was obtained at temperatures between 228 K and 245 K with the temperature dependence of lasing wavelength of 1 multiplied by (times) 0 A/deg. At 233 K, the threshold current, the output power and the differential quantum efficiency were 110 ma, 2 multiplied by (times) 2 mw and 4 multiplied by (times) 8%/facet, respectively.
