The following sections (see navigation side bar) provide a short overview about the theory of evanescent optical detection. Note, it is not our intention to provide at this point an in-depth description of the underlying physics, but rather introduce the reader to some basics.

For a detailed description of the theory, the reader is referred to the literature. Upon request, we are pleased to provide reprints of state-of-the-art reviews on this topic:
