Ultra-high-Q Microresonator with Applications towards Single Nanoparticle Sensing
Whispering-gallery mode microcavities confines light and enables enhanced light-matter interaction. They are great platforms for enhanced light-matter interactions. Using ultra-high-Q microtoroids and focusing on a phenomenon called mode splitting, we demonstrate the theory and experiments for …

Metamaterial enhanced coupling
… develops a general framework for evaluating the mode hybridization that results from their near field interaction. In fact, we find that the near field coupling is extremely sensitive to the relative orientation of the two metamaterials, and results in mode splitting between the two resonators. …

Electromagnetically active artificial material comprising multidimensional microplasma photonic crystals
… phenomena such as plasma-induced transparency, mode splitting, and Fano-like lineshapes are observed from different crystal structures under different experimental conditions. Generally, igniting plasma microcolumns in a photonic crystal will cause blue-shifting and attenuation of the Bragg …

Whispering gallery mode microcavities: from fabrication to applications
… microsphere pendulum using a whispering gallery mode (WGM) cavity-based photonic molecule scheme. In the course of implementing this scheme, microcavity devices, such as microspheres and microbubbles were studied for topics as diverse as optomechanics, photonics, laser tuning and spectroscopy. …

Advanced fibre gratings and their applications
… Starting from the Maxwell equations, the coupled-mode equations for both FBG and LPG were derived and the mode-overlap factor was analytically discussed. Computing simulation programmes utilising matrix transform method based on the models built upon the coupled-mode equations were developed, …

Exploring the pressure- and magnetic-field-induced phases of orbital-ordering KCuF3 and single molecule magnet Mn12-acetate: Crystal growth and Raman scattering studies
… the observation of temperature-dependent phonon mode softening below the putative orbital-ordering transition—suggesting that a lattice instability persists below this transition—and a previously unidentified tetragonal-to-orthorhombic structural transition near TS=50 K at temperatures slightly …

Suppression of disorder-induced scattering in optomechanical systems
… the elimination of a commonly seen normal-mode splitting effect, and by measurement of the reduction in intrinsic optical loss. More broadly, our results suggest that it is possible to dynamically suppress Rayleigh backscattering within any optical dielectric medium using time-reversal …
