A Versatile Method for Nano‐Fabrication on Diamond Film: Flexible Diamond Metasurfaces as a Demonstration

open access: yesAdvanced Optical Materials, EarlyView.
A versatile, high‐precision, non‐contaminating sugar‐transferring method is developed for nanofabrication on newly developed ultrathin and flexible diamond films. It enables the flexible all‐diamond metasurfaces, for the first time, come into the public eyes.

Few Photons Probe Third‐Order Nonlinear Properties of Nanomaterials in a Plasmonic Nanocavity

open access: yesAdvanced Optical Materials, EarlyView.
It is demonstrated that a few photons probe the nonlinear optical properties of different nanomaterials inside a plasmonic nanocavity. A simple analytical model fits the experimental result, which shows a strong dependence on the nanocavity resonance.
