Abstract

We present a novel photonic structure on the end-face of a polarization-maintaining single-mode optical fiber for broadband vector beam generation, specifically radially and azimuthally polarized beams and modes. The structure, micro-3D printed using 2-photon lithography, is sub-mm long, and features a unique design comprising complex sequential sections. Our unprecedented design enables spatial control over light's intensity profile and polarization at the optical fiber’s output, with potential significant implications for fields such as optical communications, optical trapping, microscopy, and material processing.
