Infrared Optical Switch Using a Movable Liquid Droplet

Micromachines, 2015
We report an infrared (IR) optical switch using a wedge-like cell. A glycerol droplet is placed in the cell and its surrounding is filled with silicone oil. The droplet has minimal surface area to volume (SA/V) ratio in the relaxing state.
