Tunable bipolar optical interactions between guided lightwaves

Abstract

The optical binding forces between guided lightwaves in dielectric waveguides can be either repulsive or attractive. So far only attractive force has been observed. Here we experimentally demonstrate a bipolar optical force between coupled nanomechanical waveguides. Both attractive and repulsive optical forces are obtained. The sign of the force can be switched reversibly by tuning the relative phase of the interacting lightwaves. This tunable, bipolar interaction forms the foundation for the operation of a new class of light force devices and circuits.Comment: 4 figure

Casimir forces on a silicon micromechanical chip

“…Recent theoretical analysis also predicted that the Casimir force between the beams exhibits a non-monotonic dependence on the distance to the substrate that cannot be explained by pairwise additive models of the force 28 . Because the Casimir force gradient at these distances is beyond the reach of the current setup, future experiments to reveal the aforementioned effects would require more sophisticated measurement circuitry or other detection schemes [29][30][31] to improve the sensitivity at large (42 mm) separations. Alternatively, beams and electrodes with smaller cross-sections and/or smaller beam-substrate separations can be used to generate Casimir forces that are distinguishable from the PFA and pairwise additivity at smaller distances.…”

Photon momentum transfer in inhomogeneous dielectric mixtures and induced tractor beams

“…14 Optical pulling forces provide a novel approach to gradientless optical manipulation techniques distinct from optical tweezers, [15][16][17] optical conveyors 13,18,19 and nanooptomechanical systems. 20,21 Recently, various types of tractor beams have been experimentally demonstrated using a Gaussian beam with an optical mirror (involving the interference of incident and reflected light beams in certain limited regions) 8 and using dodecane droplets sitting on a dielectric interface. 22 However, in the presence of a high-powered laser, hydrodynamic effects (uneven heat dissipation, particle absorption, temperature gradients, liquid convection, surface energy wells, etc.)…”

Effect of phase noise on the generation of stationary entanglement in cavity optomechanics

“…These schemes involve cavities and resonators at the micro-or nano-level rather than the macroscopic scale of gravitational wave detectors, and profit from the tremendous progress in micro-and nanofabrication techniques which has provided novel opportunities to engineer optomechanical devices. Some examples are toroidal optical microresonators [2], Fabry-Perot cavities with a movable micromirror [11,12], a semitransparent membrane within a standard Fabry-Perot cavity [13][14][15][16], suspended silicon photonic waveguides [17][18][19], SiN nanowires evanescently coupled to a microtoroidal resonator [20], adjacent photonic crystal wires [21], nanoelectromechanical systems formed by a microwave cavity capacitively coupled to a nanoresonator [22][23][24], atomic ensembles interacting with the mode of an optical cavity containing it [25][26][27].…”
