Abstract

The modeling, fabrication and rotation of microgears based on the principle of form birefringence, are discussed. Using a geometric anisotropy, a microgear can be fabricated of known birefringence, which may be readily rotated by manipulating the input polarization in a standard optical trap. This methodology offers a new and powerful mechanism for generating a wide range of microfabricated machines, such as micropumps, that may be driven by purely optical control. It was presented that one microgear can be used to rotate a second optically trapped microgear.
