Abstract
As opposed to the modes in an optical spherical/spheroidal microresonator, the whispering gallery modes in a long cylindrical microresonator are delocalized. Consequently, a circulating light beam that is evanescently coupled into the cylinder and experiences total internal reflection eventually radiates out along the cylinder axis. However, the self-interference of such a beam can produce a resonant mode that is strongly localized along the axial direction. Specifically, the mode characteristic width is
