Description
Technical field
The invention belongs to the optical fiber technology field, particularly a kind of based on the glimmer hand of three core hollow tubular optical fiber fabrications and the composite set of micro storage cavity.
Background technology
The light tweezer is meant the instrument that fine particle was captured and handled to the gradient force that utilizes light intensity distributions and light scattering power.Since Askin[A.Ashkin in 1986, J.M.Dziedzic, J.E.Bjorkholm, and S.Chu, Observation of a single-beam gradient force optical trap for dielectric particles, Opt.Lett.11,288-290,1986] single beam laser is introduced high-NA objective and formed the three-dimensional optical potential well, after having realized three dimensions control to particle, optical tweezer technology develops by leaps and bounds becomes important investigative technique means, and has promoted the fast development of some crossing domains.For example: fine particle catch and the fields such as assembling of carrying, skin ox level force measurement, micromechanics and micro element are widely used.At life science, optical tweezer technology is contactless with it, the intrinsic propesties of lossless detection has shown its impayable advantage especially, has brought into play enormous function for the manipulation that promotes development of life science and little life entity.The particle size that the light tweezer is captured can be rigid particles from several nanometers to tens micron, also can be soft material grains; Can be abiotic particle, also can be active somatic cell or virus.
