Abstract
A four-core single fiber optical micro-hand is proposed and fabricated
by the fiber etched method. The optical power incident and control were realized
by splice and tapered a normal single mode single core fiber with the four-core
fiber. By bending the coupling zone between the single core fiber and the
four-core fiber, one can get a rotation toque working on a micro-particle,
and can realize the particle controllable rotating. The theoretical simulation
about controlling method is worked by the Beam Propagating Method and FDTD
method, and the real-time experiment controlling photos were also given. This
four-core optical fiber micro-hand can trap and rotate the micro-particle
as ease as a human hand.
