摘要：

In the last few years, all-dielectric metasurfaces cause great interest because of their ability to create broadband perfect reflectors. It opens unique opportunities for designing of optical lenses, reflectors, and cavities for semiconductor lasers. Here, we propose a very compact design for a laser cavity based on all-dielectric metasurface perfect reflectors. We demonstrate that all-dielectric metasurface perfect reflector increases quality factor and reduces threshold power. (C) 2017 Elsevier B.V. All rights reserved.
