Abstract

We have fabricated optical metasurfaces on flexible substrates that show an optical response independent on the polarization and angles of incidence of light. The realized devices operate as ultrathin selective filters at visible frequencies, with a bandwidth of ~200 nm, and their response is robust to membrane bending for possible integration in conformal optical devices.
