Classification: CPC G  B | IPC F  G

Claim 11:
12. An optical microstructure configured to work with an optical fiber or a different substrate, the optical microstructure comprising:
a beam converter including a tapered optical guide configured to transform a gaussian optical beam into a first annular optical beam; and
an inverted cone having first and second reflection surfaces, each configured to reflect the first annular optical beam, having a radius R1, so that a resulting second annular optical beam has a radius R2 larger than the radius R1,
wherein the second annular optical beam includes 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.
