Query: Enhancement of microcavity lifetimes using highly dispersive materials   We show analytically, and numerically that highly-dispersive media can be
used to drastically increase lifetimes of high-Q microresonators. In such a
resonator, lifetime is limited either by undesired coupling to radiation, or by
intrinsic absorption of the constituent materials. The presence of dispersion
weakens coupling to the undesired radiation modes and also effectively reduces
the material absorption.
