Abstract

We propose a novel method to gather or arrange multiple micro particles by using the thermal convection effect in the water. We fabricate the fiber tip to be a nonadiabatic-tapered shape and then plate a gold film on the fiber tip. The gold film coated on the fiber tip absorbs the light output from the fiber and then generate lots of heat in the water, which causes the thermal convection. The convection forces bring the micro particles moving towards the fiber tip where the temperature is much higher. By using this thermal convection effect, we can realize the multiple micro particles gathering or arranging quickly, easily and simply.
