Abstract

A ring resonator coupled to a waveguide can be used as a highly efficient polarization converter when the input is properly polarized. We model this phenomenon and verify the predictions with a demonstration of very efficient polarization conversion $(>90\%)$ on a silica microsphere coupled to a tapered optical fiber.
