Abstract
We propose that a tapered photonic crystal waveguide design can unify optical trapping and transport functionalities to advance the controllability of optical manipulation. Subwavelength particles can be trapped by a resonance-enhanced field and transported to a specified position along the waveguide on demand by varying the input wavelength. A simulated transport ability as high as 148 (transport distance/wavelength variation) is obtained by the waveguide with tilted angle. Stable trapping of a polystyrene particle can be achieved with input power of . We anticipate that this design would be beneficial for future life science research and optomech anical applications.
