Theoretical Comparison of the Dynamical Behavior between Bulk and SQW GaAs/AlGaAs Laser with pumping of Nd: YVO4 Crysta

Abstract

In this work, a theoretical comparison was made for the dynamical
behavior of the bulk and SQW GaAs/AlGaAs lasers, in which the peak modal
gain and threshold current density are studied with varying the active region
thickness d=(0.02to 0.3)μm at two reflectivities of (R=0.32 and0.8) and the well
widths Lz=(200, 150, 100, and 75) Ǻ for the SQW laser, both at a bandgap
discontinuity of ΔEc of 0.1 eV and at a temperature of T=300oK
