Abstract :
Low threshold current CW operation of a 1.5¿1.6 ¿m-wavelength GaInAsP/InP buried heterostructure distributed Bragg reflector integrated twin guide (BH-DBR-ITG) laser was obtained up to 12°C. Single wavelength operation was obtained at a temperature range of 25 deg. The temperature dependence of lasing wavelength was 0.10 nm/deg. At 248 K, the threshold current, the differential quantum efficiency and the maximum output power were 37 mA, 16.3%/facet and 6 mW, respectively.
