Quantum-Confined Mediums Scrutinized for Narrow Linewidth Lasing
THUWAL, Saudi Arabia, July 24, 2023 — On-chip laser diodes based on quantum dot (QD) and quantum well (QW) semiconductor materials are strong candidates for applications that rely on stable laser emissions with narrow linewidth. Examples include lidar, remote sensing, and coherent communications. For these applications, the light sources deliver high power efficiency, high temperature operation, and small form factors. The heterogeneous integration of III-V lasers with SiN microresonators, aided by self-injection locking, further
