Impact of Spatial Hole Burning and Linewidth Enhancement Factor on Distributed-Feedback Quantum Cascade Lasers: A Comprehensive Design Analysis

Impact of Spatial Hole Burning and Linewidth Enhancement Factor on Distributed-Feedback Quantum Cascade Lasers: A Comprehensive Design Analysis

In this article, we use a time-domain traveling-wave approach with a coupled-mode theory to describe the dynamics of a mid-Infrared (MIR) Quantum Cascade Laser (QCL) in the Distributed-Feedback (DFB) configuration. We demonstrate that linewidth enhancement factor (LEF) and spatial hole burning (SHB)...
