Abstract
An optical beam delivery device establishes, from an optical beam, an optical trap that is moveable to different optical trap locations. The device has a first length of fiber through which the optical beam propagates along a propagation path and which has a first refractive index profile (RIP) enabling modification of the propagation path to form an adjusted optical beam movable to propagate along different propagation paths in response to different states of applied perturbation. The device also has a second length of fiber coupled to the first length of fiber and having confinement cores defining a second RIP. The confinement cores occupy different positions in, and correspond to the different optical trap locations at an output of, the second length of fiber.
