Metasurfaces for photonic devices

Abstract

Notably, metasurfaces have attracted significant attention owing to their broad capability to achieve exotic electromagnetic responses, and their potential as optical devices for wavefront control. Wide ranging materials may be used to form metasurfaces including noble and non-noble metals, oxides, ceramics, phase change materials, and semiconductors, permitting versatile and reconfigurable properties ideal for applications. In particular, applications that affect the science and technology of light—i.e., photonics—are of interest and will continue to grow in importance as our society becomes more digitally connected, but yet environmentally conscious.
