Classification: CPC G  B | IPC F  G

Claim 13:
14. A fiber optical tweezers for manipulating one or more particles, the fiber optical tweezers comprising:
an optical fiber having an end that outputs a gaussian optical beam; and
an optical microstructure attached to the end of the optical fiber and configured to receive the gaussian optical beam and generate plural single individual optical beams that act as tweezers,
wherein the optical microstructure includes,
a beam converter that transforms the gaussian optical beam into a first annular optical beam,
an inverted cone that increase a radius of the first annular optical beam to form a second annular optical beam, and
a prism that transforms the second annular optical beam into a third converging annular optical beam,
wherein the third converging annular optical beam includes the plural single optical beams that intersect at a given crossing point, outside the optical microstructure, and
wherein the plural single optical beams form an optical trap.
