Abstract

Optical metasurfaces – artificial materials composed of an array of subwavelength nanoresonators, have recently received extensive attention for their ability to enhance light-matter interaction and provide complete control of light at the nanoscale. In our work, we show how random Mie-resonant metasurfaces benefit the generation of nonlinear optical harmonics since they provide required electromagnetic field enhancement and potentially improve the nonlinear signal collection efficiency compared to the periodic metasurfaces with equivalent nanoresonator dimensions that guide newly generated light into diffraction orders.
