An annular-core single fiber optical tweezers is proposed and fabricated by fiber grinding and polishing technology. With this optical tweezers probe, more than one yeast cell can be trapped simultaneously, besides that, a large polystyrene micro sphere with diameter about 45 μm can also be trapped. This new annular core single fiber tweezers can really achieve micro particle remote trapping and manipulation and more significantly, this new tweezers can trap multi particle or large particle by a single optical fiber probe.
