【 摘 要 】

Regarded as a kind of smart surfaces, metasurfaces can arbitrarily tailor the amplitude, phase, and polarization of light. Metasurfaces usually consist of subwavelength nanoantenna or nanoresonator arrays, which are delicately designed and processed. As an ultrathin, miniaturized versatile wavefront modulation device, metasurfaces have great information capacity and can arouse the future development of highly integrated micronano optoelectronic systems. Exploiting the advantages of ultrasmall pixels, flexible design freedom, low loss, and easy processing properties, metasurfaces provide potential feasibility and new perspectives for a plethora of applications. Here we review the research progress of metasurfaces for holographic displays, polarization conversion, active modulation, linear and nonlinear wavefront modulation, and prospect the future development trend of metasurfaces.
