[ 1 ] - The Electron Stopper Layer Effect on Long-Wavelength VCSEL with AsSb-Based DBR Temperature Distribution
In this study, we have theoretically investigated the effect of electron stopper layer on internal temperature distribution of high performance vertical cavity surface-emitting laser emitting at 1305 nm. Simulation software PICS3D, which self-consistently combines the 3D simulation of carrier transport, self-heating, gain computation and wave-guiding, was used. Simulation results show that chan...
[ 2 ] - اثر تونل زنی تزریقی بر پاسخ مدولاسیون لیزرهای نقطه کوانتومی
In this paper, modulation bandwidth characteristics of InGaAs/GaAs quantum dot (QD) laser were theoretically investigated. Simulation was done by using the fourth order Runge-Kutta method. Effect of carrier relaxation life time, temperature and current density on characteristics of tunneling injection QD laser (TIL) and conventional QD laser (CL) were analyzed. Results showed that tunneling inj...
