  author={Dingding Ren and Chao Dong and David Patrick Burghoff},
The longwave infrared (LWIR) region of the spectrum spans 8 to 14 μm and enables high-performance sensing and imaging for detection, ranging, and monitoring. Chip-scale integrated LWIR photonics has enormous potential for real-time environmental monitoring, explosive detection, and biomedicine. However, realizing advanced technologies such as precision sensors and broadband frequency combs requires ultra low-loss components, which have so far remained elusive in this regime. We demonstrate that…
