Abstract :
In this work, complex-coupled DFB laser under loss coupling mechanism with multi-quantum well (MQW) structure and absorptive region inserted in the Bragg index grating was fabricated in a simpler process and the effect of quantum well numbers on the optical characteristics (threshold current, quantum efficiency) of laser diode was measured at room and high temperatures for the evaluation.
