Abstract

In this presentation, a new concept of an achromatic metafiber that focuses light coming out from the fiber facet over wavelengths of interest will be introduced. The achromatic metafiber consists of achromatic metalens microprinted on a telecommunication single-mode fiber. The 3D meta-atoms of which height is a geometric degree of freedom provide large variation of group delay, capable of realizing large time-bandwidth product. As a demonstration, direct scanning confocal imaging using the metafiber is facilitated over entire telecommunication wavelengths. Our compact achromatic metafiber may envisage many photonics applications such as hyperspectral imaging, in vivo deep-tissue imaging, and wavelength-multiplexed fiber communications.
