Abstract

We integrate infrared-to-visible upconverting nanoparticles with an asymmetric dielectric metasurface to enhance their upconversion efficiency. An upconversion enhancement of up to ~100 times is achieved. We also demonstrate infrared-to-visible upconversion imaging using fabricated devices.
