We propose and demonstrate a 2 × 2 microparticles curvilinear transport channel based on a dual self-accelerating beam generator. The device is composed of a dual-core fiber, a hollow capillary fiber, and a coreless silica fiber. The dual self-accelerating beams produced by the device propagate along the curvilinear trajectory due to the transverse accelerating property and then cross at the front of the fiber probe. The experimental results show that the yeast cell is transported along the curvilinear trajectory. By adjusting the optical power ratio of dual beams, we may control and ensure the yeast cell steers at the cross point. The proposed 2 × 2 curvilinear microparticles transport channel based on dual self-accelerating beams can realize microparticles sorting and obstacle avoidance, which means that it would be a useful tool in biology and colloidal science.
