Using a Green's function technique and the plane-wave spectrum, we formulate a classical theory for the calculation of radiative effects for a source in the presence of a planar interface or structure. The analysis focuses on understanding the roles of radiative and nonradiative energy transfer in the coupling processes and discusses the implications of modal-induced effects. This understanding is important for the design of a class of practical applications, including enhanced-sensitivity optical waveguide sensors.
