Abstract

The invention provides throughput type fiber optical tweezers based on a coaxial dual-waveguide structure and a dynamic control method. The tweezers mainly comprise a coaxial double-waveguide microstructure fiber (1), a wavelength-adjustable LD light source (2) and a standard single-mode single-core fiber (3), and are characterized in that the coaxial double-waveguide microstructure fiber (1) is coupled with the standard single-mode single-core fiber (3) in a fused-tapered mode; the other side of the standard single-mode single-core fiber (3) is connected with the wavelength-adjustable LD light source (2); and the other end of the coaxial double-waveguide microstructure fiber (1) is finely ground into a cone shape (103). Coaxial double-waveguide fiber is utilized to control particles, the throughput, emission and even resorption of the particles can be stably captured; and meanwhile, the throughput type fiber optical tweezers based on the coaxial dual-waveguide structure can capture the particles more flexibly and accurately and has adjustability, thereby greatly improving the practicability of the technology of the fiber optical tweezers.

Description

technical field [0001] The invention relates to an optical fiber optical tweezers. The invention also relates to a dynamic control method of optical fiber optical tweezers. Background technique [0002] Optical tweezers are tools for trapping and manipulating tiny particles using the gradient force and scattering force of light intensity distribution. In 1986, Askin proposed a three-dimensional optical potential well based on a single-beam laser in the article "Observation of a single-beam gradient force optical trap for dielectric particles", which is used to realize the three-dimensional space control of particles, because this beam can achieve spatial The clamping of tiny particles, hence the name "optical tweezers", this article was published in Opt.Lett.11, 288-290. Since then, the optical tweezers technology has developed rapidly and has become an important research technology, and has promoted the rapid development of several interdisciplinary fields. For example, ...
