Glass-based whispering gallery mode (WGM) microresonators are easy to produce by melting techniques. However, they suffer from surface contamination which limits their long term quality factor to only about 10E8. In this thesis, we show that an optical gain provided by erbium ions can compensate for residual losses. The optical characterization method is based on frequency-swept “Cavity-Ring-Down-Measurement”. This method can fully describe the linear properties of microcavities such as coupling regime and group delay. In compensation loss regime we demonstrate that it is possible to control the coupling regime of an ultrahigh Q-factor microresonator from undercoupling to spectral selective amplification. Under the selective amplification re...
