A new class of optical metamaterials is attracting great attention: metasurfaces, which are ultrathin twodimensional
structures that diversely manipulate light. Metasurfaces ease fabrication difficulty and avoid
the influence of absorption loss in metals more than three-dimensional optical metamaterials. In
particular, the recent development of nanoimprint lithography technologies is increasing the possibility
of practical applications of metasurfaces. Metasurfaces manipulate light waves with a huge degree of
freedom, and also enhance various optical processes through the high local density of the states of
radiation fields. We introduce recent progress in light-emitting optical metasurfaces that exhibit a large
enhancement of thermal emission and fluorescence.
