Optical phase cloaking of 700-nm light waves in the far field by a three-dimensional carpet cloak

摘要

Transformation optics is a design tool that connects geometry of space andpropagation of light. Invisibility cloaking is a corresponding benchmarkexample. Recent experiments at optical frequencies have demonstrated cloakingfor the light amplitude ("ray cloaking"). In this Letter, we demonstratefar-field cloaking of the light phase ("wave cloaking") by interferometricmicroscope-imaging experiments on the previously introduced three-dimensionalcarpet cloak at 700-nm wavelength and for arbitrary polarization of light.
