摘要

摘要

En 中文
We demonstrate 1.1W peak power at room-temperature from a double-waveguide quantum cascade laser (QCL) grown by metal-organic chemical vapor deposition. Two full broadband QCL active regions were grown on top of each other separated by thick cladding layers to reduce gain competition. Simultaneous lasing on Fabry-Perot modes separated by as much as 360 cm(-1) is obtained. This design paves the way for high-brightness broadband mid-infrared sources, as well as more complex three-terminal devices. (C) 2012 American Institute of Physics. [doi:10.1063/1.3678033]
