Evanescent wave coupling allows selective detection of cavity modes.
High-Q microtoroids enable efficient light emission from implanted ions.
Abstract
We report on light emission from high-Q neodymium-implanted silica microtoroids. Following the description of the fabrication process of microtoroids, neodymium light emission is analysed. This emission is coupled to various cavity modes. Using evanescent wave coupling we achieve selective detection of Whispering Gallery Modes of a microtoroid.
