Theoretical Study of a Two-Dimensional Optical Trapping of a Microsphere by the Laser Beam from an Optical Fiber end Inserted into a Sample Cell at an Angle

Abstract

Optical forces exerted on a microsphere by the laser beam from an optical fiber inserted at an angle were theoretically analyzed. From these results, we verified that the laser beam emitted at an angle from an optical fiber could obtain a two-dimensional optical trapping of a microsphere on the surface of a sample cell.
