Abstract
In this paper, an optical trapping method using optical fiber (Optical Fiber Trapping Method) is proposed. This optical fiber trapping method has many following merits, if the microscopic objects are optically trapped near the fiber end. (i) Optical trapping systems using optical fiber are simple and inexpensive. (ii) Optical sources can be changed easily using optical connectors, (iii) Trapping point is easily noticeable, because a fiber end points out the focal point.
Experimental results are as follows. (i) Optical trapping of a micro-object is easily achieved using an optical fiber whose end is polished to a tapered spherical end. (ii) Optically trapped object can be freely transferred in 2-D plain, synchronized to the trapping fiber. (iii) Optical manipulation characteristics for the optically trapped object depend on the distance between the trapping fiber end and the micro-object.
