Abstract
We propose and demonstrate a simple method to generate a Bessel-like beam by using a graded-index multimode fiber. We splice a single-mode fiber and a graded-index multimode fiber with a defined offset (Îx=20 μm), adjust the length (L) of the graded-index multimode fiber to be 400 μm, and then we can produce a Bessel-like beam with the transverse acceleration of 0.15464 μmâ2. The Bessel-like beam has the transverse self-accelerating properties which provides a new method for micro particles to be transported in a bending trajectories. This transverse self-accelerating Bessel-like beam generator based on the graded-index multimode fiber constitutes a new development for high-precision micro particles experiments and manipulations with its simple structure, high integration and small size.
