We have fabricated 1.3 μm AlGaInAs/InP multi-quantum-well(MQW)ridge waveguide lasers with both junction-up and junction-down mounting, and compared the thermal resistance(R_<th>)and other laser characteristics such as the maximum CW operating temperature(T_<max>), characteristic temperature of threshold current(T_0), and the maximum CW output power(P_<max>). The thermal resistance was found to be 73.6 K/W and 43.5 K/W for junction-up and -down mounting, respectively. T_0, T_<max> and P_<max> were also improved by 7K, 20℃ and 20% in the junction-down configuration, respectively, which is due to a reduction of the thermal resistance. A CW T_<max> as high as 185℃ has also been achieved with 350-μm-long high-reflective-coated lasers, which is one of the highest CW operation temperature reported to date for InP-based long wavelength lasers.
