Abstract :
The driving current of a 1.3-μm beam-expander (BEX) integrated laser diode was dramatically reduced by using n-type modulation doped multiple-quantum-well active layer. The threshold current at 85°C was 28.0 mA and the slope efficiency was 0.3 W/A. In a temperature range from -30°C to 85°C, a record high characteristic temperature T 0 of 86. 1 K and the slope efficiency degradation Δη as low as (-30°C-85°C)-1.6 dB were achieved
