The efficiency of a memory, which is the focus of this work, is defined as the probability of successful storage and subsequent retrieval of the information. This thesis reports an experiment performed towards making a high efficiency quantum memory by using a cavity enhanced Atomic Frequency Comb (AFC) protocol, implemented in a waveguide in a rare-earth ion doped crystal. Our measurements identified the obstacles that have to be overcome to achieve that aim. Exploiting the cavity dynamics, we managed to estimate the essential parameters in implementation of the scheme. The investigations give a valuable insight into the protocol and the ways to exploit its full potential. Furthermore, the analysis of the experimental observations leads to proposals that may serve as alternatives to current ways of implementing the protocol.engUniversity of Calgary graduate students retain copyright ownership and moral rights for their thesis.
