| 1 | Hybrid graphene metasurfaces for highspeed mid-infrared light modulation and single-pixel imaging显示文摘During the past decades,major advances have been made in both the generation and detection of infrared light;however,its efficient wavefront manipulation and information processing still encounter great challenges.Efficient and fast optoelectronic modulators and spatial light modulators are required for mid-infrared imaging,sensing,security screening,communication and navigation,to name a few.However,their development remains elusive,and prevailing methods reported so far have suffered from drawbacks that significantly limit their practical applications.In this study,by leveraging graphene and metasurfaces,we demonstrate a high-performance free-space mid-infrared modulator operating at gigahertz speeds,low gate voltage and room temperature.We further pixelate the hybrid graphene metasurface to form a prototype spatial light modulator for high frame rate single-pixel imaging,suggesting orders of magnitude improvement over conventional liquid crystal or micromirror-based spatial light modulators.This work opens up the possibility of exploring wavefront engineering for infrared technologies for which fast temporal and spatial modulations are indispensable. | Beibei Zeng Zhiqin Huang Akhilesh Singh Yu Yao Abul K.Azad Aditya D.Mohite Antoinette J.Taylor David R.Smith Hou-Tong Chen | 2018 | Light(Science & Applications)2018，7，1： | 13 |
