14 February 2007 The maximum group delay in a resonator: an unconventional approach
Author Affiliations +
We introduce a definition of group velocity for a system with a discreet spectrum and apply it to a linear resonator. We show that a positive, negative, or zero group velocity can be obtained for light propagating in the whispering gallery modes of a microspherical resonator. The associated group delay is practically independent of the ring-down time of the resonator. We demonstrate "stopped light" in an experiment with a fused silica microsphere.
