The model is made simple to make it suitable as fast-design-tool for multiple quantum well electroabsorption modulators. A complete and self-consistent model of the quantum confined Stark effect (QCSE) is also presented. Scalar Schrodinger equation is solved in the presence of static electric field. The position of heavy hole (hh) exciton peak and its shift (stark shift) is calculated numerically, considering the effect of the number, width and height of quantum wells. Coupling effect between the quantum wells in the calculations was considered for the first time.","PeriodicalId":206987,"journal":{"name":"IEEE/LEOS 3rd International Conference on Numerical Simulation of Semiconductor Optoelectronic Devices, 2003.

Various material and structural parameters are used, such as the injection current I, the grating reflectivity R/sub g/, the linewidth enhancement factor /spl alpha/, and a/spl xi//V, where a is the tangential coefficient of the linear gain, /spl xi/ is the field confinement factor and V is the volume of the active region. The simulation is performed based on a new time delay model for SLs, which is applicable under strong OFB. The simulation results show that the lasing operation of SLs under strong OFB is classified into continuous wave (CW), chaos and pulsation depending on the operating conditions. The differences and characteristic features of each lasing operation in the regime of strong OFB are given.","PeriodicalId":206987,"journal":{"name":"IEEE/LEOS 3rd International Conference on Numerical Simulation of Semiconductor Optoelectronic Devices, 2003.
