Abstract

In this work FZL and FPL fabricated using Focused Ion Beam milling on the top of custom-made optical fibers are presented. Primary, single mode fibers are spliced to a segment of multimode fiber allowing to expand the core region. Subsequently, FZL and FPL with several focusing distances are milled on the top of the fibers. In this regard, the zone and phase plates offer distinct focusing characteristics which are here presented and analyzed. Moreover, the output optical intensity field of the FPL and FZP are evaluated and validated using an implementation of the Finite Differences Time Domain (Lumerical). Lastly, some considerations on the use of the tips as fiber optical tweezers are given.
