  • Abstract
    In this work, the performance characteristics of a designed oxide confined 420nm InGaN based multiple quantum well (MQW) blue-violet laser have been optimized and presented by varying differential gain. The material gain of In0.1227Ga0.8773N/Al0.08Ga0.92N MQW edge emitting laser (EEL) has been theoretically obtained. The peak material gain obtained from the analysis has been used to study the performance of the designed oxide confined laser. The lower value of the threshold current has been obtained as 3.4mA for the designed oxide confined laser. The steady state output power is 71.68mW and the modulation bandwidth is 14GHz at a differential gain of 1x10-16 cm2. By increasing the differential gain up to 5x10-16 cm2 a maximum value of output power is obtained as 73.37mW and a maximum modulation bandwidth is obtained as 28GHz. Thus, a better performance of the designed oxide confined laser has been observed by varying the differential gain.
