Abstract

In this paper we present a method to transfer ultra-Thin polymer-encapsulated metallic metasurfaces onto optical fibers to enable ultra-Thin imaging devices. The metasurface is first produced by conventional e-beam lithography on a silicon substrate and encapsulated by a resist layer. After patterning the resist layer to the target shape, the encapsulated metasurfaces are peeled off from the substrate and then glued onto the tip of a single-or multi-mode optical fiber. As a proof-of-concept we demonstrate a nanowire grating polarizer on the tip of an optical fibre. This method will allow the design and fabrication of multi-layered metasurface endoscopic devices for imaging and sensing.
