Paper Abstract

We explore the possibility of using optical tweezers to enable all optical control of optofluidic circuits. Optically trapped microspheres can be used as microlenses for optical signal switching and steering. By using cantilevers instead of microspheres we provide a method for robust and stable placement of switching elements in the optofluidic circuits. Cantilevers made of tapered optical fiber and polydimethyl siloxane are demonstrated. We also show that it is possible to use transverse optical tweezer beams to load silica beads into the hollow core photonic crystal fibers for tuning their transmission properties.
