“…[5][6][7] Also, the possibilities of creating microstructures by optical binding and resonance effects have been discussed [8][9][10][11][12] as well as the control of particles by evanescent waves. 13,14 Only a few works exist on the interpretation, prediction and control of the optical force acting on a small particle on a plane surface.…”

By using a method, previously established to calculate electromagnetic fields, we compute the force of light upon a metallic particle. This procedure is based on both Maxwell's Stress Tensor and the Couple Dipole Method. With these tools, we study the force when the particle is over a flat dielectric surface. The multiple interaction of light between the particle and the surface is fully taken into account. The wave illuminating the particle is either evanescent or propagating depending an whether or not total internal reflection takes place. We analyze the behaviour of this force on either a small or a large particle in terms of the wavelength. A remarkable result obtained for evanescent field illumination, is that the force on a small silver particle can be either attractive or repulsive depending on the wavelength. This behaviour also varies as the particle becomes larger.

“…Compound, microcavity systems are sometimes called photonic molecules [14,15,16]; and herein this is a particularly apt interpretation. Hybridized orbitals of an electronic system are replaced by optical supermodes of the compound (photonic molecule) system; and transitions between their corresponding energy levels are induced by a phonon field.…”

Phonon Laser Action in a Tunable Two-Level System

et al. 2010

The phonon analog of an optical laser has long been a subject of interest. We demonstrate a compound microcavity system, coupled to a radio-frequency mechanical mode, that operates in close analogy to a two-level laser system. An inversion produces gain, causing phonon laser action above a pump power threshold of around 50 µW. The device features a continuously tunable, gain spectrum to selectively amplify mechanical modes from radio frequency to microwave rates. Viewed as a Brillouin process, the system accesses a regime in which the phonon plays what has traditionally been the role of the Stokes wave. For this reason, it should also be possible to controllably switch between phonon and photon laser regimes. Cooling of the mechanical mode is also possible. [10]. However, only recently has phonon laser action been reported using a harmonicallybound magnesium ion [11]. Here, using a compound microcavity system, a phonon laser that operates in close analogy to a two-level laser system is demonstrated. The approach uses intermodal coupling induced by radiation pressure [12], and can also provide a spectrally selective means to detect phonons. Moreover, there is currently great interest in optomechanical cooling [13] and evidence of intermodal cooling is observed.

“…It is a manifestation of the well known phenomenon of the normal mode splitting in coupled harmonic oscillators. Similar effects have been reported in photonic systems [6,7]. We report the observation of the acoustic mode splitting of a phononic molecule by using high-resolution Raman scattering.…”
