Optical Cavities are used extensively to enhance
processes that depend on the interaction between light and matter due to their
strong frequency selectivity and sharp dispersion near resonance. Most of the
cavities that are used in optics have relatively large dimensions and modest Qs
(<10,000). A new type of optical resonator, which has been the focus of
increased attention this year as a possible photonic device, is the spherical
dielectric microparticle (SDM). This tiny cavity, with a diameter of a few
microns to several hundred microns has resonances with reported Qs approaching
1x109. The combination of high-Q resonances in a very small volume offers new
possibilities for photonic devices.
