Low Power Consumption Substrate-Emitting DFB Quantum Cascade Lasers

Low Power Consumption Substrate-Emitting DFB Quantum Cascade Lasers

Abstract In the present work, an ultra-low power consumption substrate-emitting distributed feedback (DFB) quantum cascade laser (QCL) was developed. The continuous-wave (CW) threshold power dissipation is reduced to 0.43 W at 25 °C by shortening the cavity length to 0.5 mm and depositing high-refle...
