Theoretical Investigation of an Optical Vibration Using Laser Beams from Optical Fibres Inserted at an Angle of 35 degrees

摘要

In this paper, we propose an optical manipulation technique of microscopic particles using plural optical flat-top fibres, inserted into a sample cell at an angle of 35 degrees, and verify that an optically trapped object can be optically vibrated by controlling laser power emerging from optical fibres without moving the optical fibres. We theoretically analyzed the optical forces exerted on a microsphere, a 10μm diameter polystyrene particle (refractive index 1.59), by laser beams. From these theoretical results, we verify that our proposed optical manipulation technique is useful for the manipulation of biological cells.
