Abstract

Through optimal thermal annealing of the active region of a 1.3 μm GaInNAs/GaAs single-quantum-well laser diode, we obtained a characteristic temperature (T0) of 215 K under pulsed operation from 20°C to 80°C. This is the highest yet reported value for a 1.3-μm semiconductor laser. Even under continuous-wave operation, the T0 was as high as 147 K. The lasing-wavelength change with temperature was as small as 0.39 nm/°C, indicating the excellent stability for a GalnNAs laser diode with T0 of over 200 K. These results demonstrate that GaInNAs is a promising material for fabricating long-wavelength laser diodes used for opticalfiber communications.
