Tapered Quantum Cascade Laser Arrays Integrated with Talbot Cavities
Autor: Yue Zhao, Jin-Chuan Zhang, Feng-Min Cheng, Dong-Bo Wang, Chuan-Wei Liu, Ning Zhuo, Shen-Qiang Zhai, Li-Jun Wang, Jun-Qi Liu, Shu-Man Liu, Feng-Qi Liu, Zhan-Guo Wang
Publikováno v: Nanoscale Research Letters, Vol 13, Iss 1, Pp 1-7 (2018)
Abstract Power scaling in broad area quantum cascade laser (QCL) usually leads to the deterioration of the beam quality with an emission of multiple lobes far-field pattern. In this letter, we demonstrate a tapered QCL array integrated with Talbot ca

Low Power Consumption Substrate-Emitting DFB Quantum Cascade Lasers
Autor: Chuan-Wei Liu, Jin-Chuan Zhang, Zhi-Wei Jia, Ning Zhuo, Shen-Qiang Zhai, Li-Jun Wang, Jun-Qi Liu, Shu-Man Liu, Feng-Qi Liu, Zhan-Guo Wang
Publikováno v: Nanoscale Research Letters, Vol 12, Iss 1, Pp 1-5 (2017)
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 th

GaSb surface grating distributed feedback interband cascade laser emitting at 3.25 µm
Autor: Chao Ning, Rui-Xuan Sun, Shu-man Liu, Jin-Chuan Zhang, Ning Zhuo, Jun-Qi Liu, Li-Jun Wang, Shen-qiang Zhai, Feng-Qi Liu, Zahn-Guo Wang
Publikováno v: Optics express. 30(16)
A second-order distributed feedback interband cascade laser emitting at 3.25 µm was designed, grown, and fabricated. By coherent epitaxy of a GaSb cap layer instead of the conventional thin InAs cap on top of the laser structure, a high-quality surf
