Abstract
In this paper, we demonstrate that micro-particle is able to be transported by two types of integrated photonic devices; one is directional couplers and the other is multimode interferometers. Micro-particles are propelled by the evanescent wave and guided by the interference pattern of optical field inside the devices. By properly designing the device length and operation wavelength, micro-particles can be switched to either one of the output ports connecting the devices. © 2012 IEEE.
