A 1.3-µm GaInNAs/GaAs Single-Quantum-Well Laser Diode with a High Characteristic Temperature over 200 K

Abstract
We have obtained a high characteristic temperature (T 0) of 215 K from a 1.3 µm GaInNAs/GaAs single-quantum-well laser under pulsed operation at 20°C to 80°C. To our knowledge, this T 0 is the highest yet reported for 1.3 µm band edge emitters suitable for optical-fiber communication systems. The use of GaInNAs as an active layer is, therefore, very promising for the fabrication of long-wavelength laser diodes with excellent high-temperature performance.
