Abstract

Whispering gallery mode devices have emerged as a powerful class of optical devices in which light-matter interactions are significantly enhanced within micron-scale structures, making them an ideal platform for both fundamental science and applications such as advanced sensors, low-threshold lasers and nonlinear optics, just to name a few. Typically, fibers tapers or prisms are used as optical couplers for the resonators. We demonstrate angle-polished fibers as an alternative option to efficiently couple light to a high-quality whispering-gallery resonator. Angle-polished fibers offer the advantage of rapid fabrication, increased mechanical stability versus fiber tapers, and the ability to tune the excitation angle of light. We demonstrate the use of angle-polished fibers for coupling light out of a whispering-gallery device as well as a rapid, low-cost method for fabricating the couplers.
