چکیده

We consider the resonant optical force acting on a pair of transparent microspheres by the excitation of morphology-dependent resonance (MDR). The bonding and antibonding modes of the MDR correspond to strong attraction and repulsion, respectively. The dependence of the force on separation and the role of absorption are discussed. At resonance, the force can be enhanced by orders of magnitude such that it will dominate other relevant forces. We found that a stable binding configuration can be induced by the resonant optical force.

Effect of Angular Velocity on Sensors Based on Morphology Dependent Resonances

We carried out an analysis to investigate the morphology dependent optical resonances shift (MDR) of a rotating spherical resonator. The spinning resonator experiences an elastic deformation due to the centrifugal force acting on it, leading to a shift in its MDR. Experiments are also carried out to demonstrate the MDR shifts of a spinning polydimethylsiloxane (PDMS) microsphere. The experiment...

Morphology-Dependent Resonances and Their Applications to Sensing in Aerospace Environments

This paper reviews recent developments in Morphology—Dependent Resonance (MDR)—based sensors for aerospace applications. The sensor concept is based on the detection of small shifts of optical resonances (also called the whispering gallery modes or WGM) of dielectric spheres caused by external effects. Recent developments in MDR-based micro-optical sensors for temperature, force, pressure and c...

Asymptotic estimations of power thresholds and anti-Stokes frequency of laser induced thermal scattering in microresonators

A derivation of the asymptotic expressions for the threshold intensity of laser induced thermal scattering in silica microresonator when illuminated with a plane wave is present. The calculation of anti-Stokes thermal combination frequencies are made for the spherical high Q-factor microresonators. The three modes regime of nonlinear interaction is considered. One pump-driven, two signal modes,...

Spiral morphology-dependent resonances in an optical fiber: effects of fiber tilt and focused Gaussian beam illumination.

Spiral morphology-dependent resonances have been observed in a tilted optical fiber. The polarization-preserving and the cross-polarized elastic-scattering spectra for plane-wave illumination show that the wavelengths of the resonances are blueshifted quadratically as the fiber tilt angle increases. When a focused Gaussian beam illuminates the fiber at its edge, the resonances are blueshifted a...
