High characteristic temperature (To = approximately 322 K) is demonstrated near room-temperature with V-grooved. AlGaAs-GaAs multiple quantum wire (QWR) lasers grown by flow rate modulation epitaxy. The wavelength tuning rate of temperature Δλ/ΔT measured for 300 μm long uncoated lasers is approximately 0.19 nm/°C and that of injection current Δλ/ΔI is extremely small, in between 0.02 and 0.03 nm/mA in the temperature range 10 to 70 °C.
