Nonreciprocal and temperature-tunable light absorption in AlAs/ITO/GaAs Hybrid Metasurfaces
Yi Chen, Lin Cheng, Kun Huang +2
The single-band high-efficiency light absorption of nanostructures finds extensive applications in var ious fields such as photothermal conversion, optical sensing, and biomedicine…
Double-optical phase-transition in a three level Rydberg state in thermal Rubidium vapor
Lin Cheng, Kun Huang, Chunhui Shao +3
We report on the observation of electromagnetically induced transparency (EIT) with intrinsic phase transitions in a three-level ladder system within rubidium atomic vapor. The obs…
Tunable Absorption in Near Infrared Based on Indium Tin Oxide
Shuaishuai Hou, Lin Cheng, Nan Meng +4
We propose a serrated ultra-broadband infrared absorber based on the multi-layer repetitive stacking of indium tin oxide (ITO) and silicon materials. This absorber achieves continu…
Modulation of supernarrow EIT pair via atomic coherence
Lin Cheng, Zhiyuan Xiong, Shuaishuai Hou +4
We report the phenomena of electromagnetically induced transparency (EIT) and electromagnetically induced absorption (EIA) using two identical beams in rubidium atomic vapor. The Î…
