Phys. Rev. E 71, 026602 (2005) [5 pages]Enhancement of microcavity lifetimes using highly dispersive materialsReceived 10 December 2003; revised 25 August 2004; published 8 February 2005 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. © 2005 The American Physical Society URL:
