文摘We present and demonstrate a multifunctional single-fiber optical tweezer for particle trapping and transport.The fiber probe of fiber optical tweezers is constructed as a planar structure.Laser sources with wavelengths of 650 nm and 980 nm in a single-mode fiber excite the linearly polarized LP11mode and LP01mode beams,respectively.These two laser beams can achieve non-contact trapping and long-distance transport of particles after passing through a flat-facet fiber probe,respectively.This structure makes it possible to perform non-contact trapping and transport of particles by combining multiple wavelengths and multiple modes.
