Abstract

The maximum direct modulation bandwidth in semiconductor lasers is described by the K-factor.¹ In quantum-well (QW) semiconductor lasers, it has recently been recognized that carrier transport is significant in limiting this bandwidth.² Specifically, the effects of carrier transport have been described by using a reservoir model³ with the introduction of two phenomenological time constants, ${\tau }_{\text{cap}}^{\text{E}}$ and ${\tau }_{\text{esc}}^{\text{E}}$.
