Abstract Details

2006, MS, University of Cincinnati, Engineering : Electrical Engineering.
This thesis is undertaken to understand the trade-off in the performance of semiconductor lasers with increase in well number. Five and seven quantum well InAlGaAs lasers operating at 1300nm were investigated. Seven quantum well lasers showed better optical confinement and characteristic temperature than the five quantum well lasers. Increase in well number lowers threshold current and improves optical confinement factor, characteristic temperature, net gain and material gain with trade off in slope efficiency, differential quantum efficiency and cavity loss. Design curves were plotted to aid laser designers to understand the performance trade off in increasing the well number. Seven quantum well lasers exhibited low threshold current of 13.8mA and high characteristic temperature of 71°c. Five quantum well lasers showed high slope efficiency of 0.198W/A and a low cavity loss of 18/cm. This study also helps in optimizing the number of quantum wells for the given cavity length. .
