Optically Levitated Conveyor Belt Based on Specular-Reflection Photonic Nanojet

We have proposed an optically levitated conveyor belt based on specular-reflection photonic nanojet (s-PNJ). The trapped particles can suspend in the water and transport with the movement of hot spots caused by the deflection of exciting light. In addition, the rate of successful particle transporting can be up to 96.3% after the distance of 50 mu m when the power intensity is as low as 0.2 mW/mu m(2).
