(color online) Schematic models of SD fiber structures, respectively, with (a) flat endface and (b) oblique endface (with an angle of θ as depicted) for numerical simulations. Inset shows Cartesian coordinates. Light in the guided mode of the SD fiber transports from left to right when the endface ignites optical force and mechanical motion of the SD fiber.
