Paper Abstract

An optical actuator has some interesting characteristics, such as no generation of magnetic noise and receiving the energy remotely. A novel micromanipulator using photothermal effect is proposed. It consists of three optical fibers. One end of the fiber is cut for a bevel and painted with black color. A photothermal effect is occurred responding to the incident beam at the end of optical fiber. This effect makes the end of fiber stretching vibration. It can release a ball with 2.5 mm of diameter and a microlens currently held by light energy. The mechanism of photothermal vibration is also studied.
