An optical switching system that uses a robotic mechanism and an intersecting waveguide with grooves requires contact-free removal of the matching oil from the grooves. This suction phenomenon was studied by experimentally sucking liquid from a Hat plate by using a subsonic gas How through a microcapillary tube. The results show that the shape of the liquid during suction is constantly changing and the shape immediately before uptake depends little on the amount of liquid on the plate. They also show that the liquid is not sucked until it assumes a particular shape. Therefore, the liquid shape indicates the amount of remaining liquid that cannot be removed by suction. The tube shape that minimizes the amount of remaining liquid varies according to the distance between the tube and the plate, and the amount of remaining liquid depends little on the kinetic viscosity of the liquid.
