Paper Abstract
Compact Quantum Cascade Laser waveguides have been analyzed using the full-vectorial finite element method. Modal
intensity profiles, detailed power confinements and loss factors have been characterized for waveguides based on
GaSb/AlGaSb multiple quantum well structures. Variations in these key parameters were also further investigated whilst
varying the semiconductor doping concentration. Higher order modes having a low propagation loss were also shown.
