Method for determination of capture velocity of charge carriers into quantum well in semiconductor laser

Abstract: A simple method for the determination of the capture velocity of charge carriers from a three-dimensional (3D) region (waveguide region) into a 2D region (quantum well) is proposed. The method is based on measurement of the threshold current density and internal differential quantum efficiency in a semiconductor laser structure. The method also allows determining the 2D carrier density in a quantum well, which is otherwise not easy to measure in a multilayer laser structure.

“…on the compositions of the QW and OCL materials; they also depend on the QW width. In [13,14], we evaluated the electron capture velocity for our experimental laser structures using our theoretical model. Another key component of our theoretical model is the internal optical absorption loss, which depends on the electron and hole densities in the OCL [15]…”
