Abstract :
In this paper we will report analysis of a quantum-well (160 Aring QW) Transistor Laser with 150 mum cavity length using a charge control model in order for modifying QW location through base region. The analysis shows significant enhancement, at constant bias currents, in optical bandwidth due to moving the QW in the direction of collector-base junction. No remarkable resonance peak, limiting factor in laser diodes, is observed throughout this modification in TL structure. The method simulated here could be utilized for TL structure design.
