For those frequencies below the cutting point, the launched source cannot propagate but decays exponentially along the waveguide.…”

Usually, an unfocused light beam, such as a paraxial Gaussian beam, can exert a force on an object along the direction of light propagation, which is known as light pressure. Recently, however, it was found that an unfocused light beam can also exert an optical pulling force (OPF) on an object toward the source direction; the beam is accordingly named an optical tractor beam. In recent years, this intriguing force has attracted much attention and a huge amount of progress has been made both in theory and experiment. We briefly review recent progress achieved on this topic. We classify the mechanisms to achieve an OPF into four different kinds according to the dominant factors. The first one is tailoring the incident beam. The second one is engineering the object's optical parameters. The third one is designing the structured material background, in which the light-matter interaction occurs, and the fourth one is utilizing the indirect photophoretic force, which is related to the thermal effect of light absorption. For all the methods, we analyze the basic principles and review the recent achievements. Finally, we also give a brief conclusion and an outlook on the future development of this field.

“…Presently, scientists are also interested in using guided waves to trap and manipulate small particles [10][11][12]. Particles can be transported bidirectionally in the longitudinal direction by tuning the frequency of the light wave [12,13]. Gold nanoparticles of different sizes can be sorted out bidirectionally in the longitudinal direction by dual wavelength counter-propagating evanescent waves, where the red-shift of the plasmon resonance for increased size of particles allows the movement of different sized nanoparticles in opposite direction [14].…”

Optical trapping and manipulation of dielectric particles on the surface of a dielectric prism using TE plane waves are demonstrated in the Rayleigh scattering regime. The interference of four counter propagating evanescent waves forms a standing wave on the planar surface and the trapping is realized based on the gradient force. Two mirrors are used to manipulate the trapped particles in any arbitrary direction on the surface. The required trapping potential and the irradiance within the Rayleigh scattering regime are computed. A hypothesis is developed to pull the particles at a maximum force toward the surface for further demonstration of this configuration. The standing wave on the surface of the prism using TE Gaussian beams are demonstrated for practical illustration of this study.

“…Furthermore, to achieve enhanced forward scattering, multipoles must be simultaneously excited, which renders the optical pulling material-and size-dependent [3,6,10]. These problems can be partially solved by changing the background from free space to a waveguide [11][12][13][14][15][16][17][18] or metamaterials [19], such as using the guided waves supported in a double-mode photonic crystal waveguide [16][17][18].…”

This paper proposes a new method to achieve robust optical pulling of particles by using an air waveguide sandwiched between two chiral hyperbolic metamaterials. The pulling force is induced by mode conversion between a pair of one-way-transport surface-arc waves supported on the two metamaterial surfaces of the waveguide. The surface arcs bridge the momentum gaps between isolated bulk equifrequency surfaces (EFSs) and are topologically protected by the nontrivial Chern numbers of the EFSs.
