Abstract

In this Letter, we show stable suspension and directional manipulation of microdroplets on a liquid surface employing simple-mode fiber with a Gaussian beam at 1480-nm wavelength using the photothermal effect. The intensity of the light field generated by the single-mode fiber is used to generate droplets of different numbers and sizes. In addition, the effect of the heat generated at different heights from the liquid surface is discussed through numerical simulation. In this work, the optical fiber is not only free to move at any angle, solving the difficulty that a certain working distance is needed to generate microdroplets on free space, it can also allow the continuous generation and directional manipulation of multiple microdroplets, which is of tremendous scientific relevance and application value in promoting the development and cross-fertilization of life sciences and other interdisciplinary fields.

Visualization 1       The number of droplets increases with the increase of power.
Visualization 2       The optical field moves with the light and the location of the photothermal region moves with the fiber, and the rising hot vapor stream follows the location of the photothermal, which eventually leads to the resulting micro-droplets following the fi
