Abstract

We suggest a new way of using Bessel beams to achieve n-dimensional optical control of high-refractive index microparticles. Although classic optical trapping generally uses bulk optics, this study uses small fiber optics with maximized efficiency. The Bessel beams follow the propagation axis, and the gradient force generated during this process creates an axial optical power that enables the confinement of particles. Due to the non-diffractive property of this beam, the beam diameter is much longer than that of a general Gaussian beam and has a self-healing property that suppresses the deformation of the beam.
