Abstract

The laser beam trapping method is considered to be useful for manipulation of microscopic objects and biological cells because of noninvasive technology. Its operation principle is based upon the electromagnetic momentum preservation. In this paper, novel optical trapping technologies using plural optical fibers[1][2] are reported. This optical fiber trapping method has following merits: (i) optical trapping systems using optical fibers are simple and inexpensive, (ii) trapped objects can be moved easily and freely synchronized to the trapping fiber, (iii) optical sources can be changed easily using optical connectors.
