Cavity Length Scaling of Quantum Cascade Lasers for Single-Mode Emission and Low Heat Dissipation, Room Temperature, Continuous Wave Operation

Cavity Length Scaling of Quantum Cascade Lasers for Single-Mode Emission and Low Heat Dissipation, Room Temperature, Continuous Wave Operation

Single-mode operation of Fabry-Perot quantum cascade (QC) lasers is achieved through the systematic shortening of the cavity length from 764 to 110 μm. The increased mirror loss is mitigated using highly reflective (HR) metallic facet coatings (R >; 95%). Ultrashort cavity QC laser...
