Paper Abstract

Intense optical fields can induce significant forces "between" particles. In analogy with atomic physics, the resonant modes of a single particle play the role of electronic orbitals and, like their electronic counterparts, could lead to bonding and antibonding interactions between neighboring particles. In absence of absorbing or "Mie"-like resonances, light forces on small particles are, in general, very small. However, as we will show, when the fields are confined in quasi-one-dimensional waveguide structures, the coupling of the scalar dipolar field with the waveguide modes leads to a resonant total reflection close to the threshold of a new propagating mode. These resonant modes are shown to lead to unusual strong optical interactions between particles.
