Enhanced Beam Quality of Overlapped Angled Cavity Quantum Cascade Lasers with Integrated Notches
2022 28th International Semiconductor Laser Conference (ISLC)
Year: 2022 | Conference Paper |
Cited by: Papers (1)
Angled Cavity Quantum Cascade Lasers have been demonstrated to generate enhanced brightness with power scaling of broad area laser cores while maintaining good beam quality. A further improvement of beam quality is demonstrated in overlapped angled cavity quantum cascade with the introduction of notches.Show More
Floquet-Bloch Analysis for Distributed Feedback Quantum Cascade Lasers With a Non-Rectangular Top-Metal Grating Profile
A detailed description of a numerical model based on the Floquet-Bloch approach for designing distributed feedback quantum cascade lasers with a non-rectangular top-metal grating profile is presented. The numerical methods resulting in efficient numerical calculations and allowing for the accounting of over thirty partial waves are discussed. The practical examples show that a change in grating sh...Show More

IEEE Photonics Technology Letters
Cited by: Papers (13)
Experimental data for 15-stage 5.6-μm quantum cascade lasers based on Al0.78In0.22As/In0.69Ga0.31As active region composition are presented. Pulsed slope efficiency, threshold current density, and wall-plug efficiency for a 2.1 mm × 10.4 μm device with a high reflection-coated back facet were measured to be 1.45 W/A, 3.1 kA/cm2, and 18%, respectively. Corresponding continuous wave values for the s...Show More
