In applications such as optical coherence tomography, there is a need both to achieve large depth of field by light shaping and to maintain ultracompact form factors. Flat metasurfaces on optical fibers can achieve such requirements, with designs suc... Read More about Diffractive metasurface light-shaping from fiber endoscope probes for increased depth of field.

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...
