Description
Summary:We present a novel and efficient approach to generating Bessel-like beams through fabricating self-growing polymer microtips at the facet of single-mode fibers. To produce these beams, the length and shape of microtips were precisely optimized. Specifically, the convex droplet height and its photopolymerization parameters feature prominently in Bessel-like beams via microtips. A wide conversion bandwidth of the microtips and self-healing properties of the produced Bessel-like beam were also investigated in detail. Our microtips provide an effective, low-cost, and ultra-compact way for Bessel-like beams generation.
