Abstract
We develop a theory for the quantum-fluctuation spectrum of nonlinearly interacting whispering-gallery modes in a cylindrical microresonator with small radius variations. We show that the nonuniform axial spatial distribution of the modes can be used to optimize the coupler position, enabling both efficient pumping of the central mode and strong squeezing of correlated photon pairs in the sidebands.
