High efficiency near diffraction-limited mid-infrared flat lenses based on metasurface reflectarrays
Shuyan Zhang, Myoung-Hwan Kim, Francesco Aieta +9
A limiting factor in the development of mid-infrared optics is the lack of abundant materials that are transparent, low cost, lightweight, and easy to machine. In this paper, we de…

Coherent instabilities in a semiconductor laser with fast gain recovery
C. Y. Wang, L. Diehl, A. Gordon +9
We report the observation of a coherent multimode instability in quantum cascade lasers (QCLs), which is driven by the same fundamental mechanism of Rabi oscillations as the elusiv…
